 <title>Renewable energy using artificial trees made of nanoleaves</title>
 <link>http://www.nanovip.com/node/53868</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Solar Botanic will introduce artificial trees that make use of renewable energy from the sun and wind, they are an efficient clean and environmentally sound means of collecting solar radiation and wind energy.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Solar Botanic will introduce artificial trees that make use of renewable energy from the sun and wind, they are an efficient clean and environmentally sound means of collecting solar radiation and wind energy.&lt;/p&gt;
&lt;p&gt;Here at Solar Botanic, we&#039;ve amassed a wealth of information relating to Solar Botanic Trees and Nanoleaves and the field of photovoltaic thermovoltaic and piezovoltaic technology. You will be amazed how efficient our Trees are, how they make use of light, heat and wind and turn it into useable electricity for your home or car.&lt;/p&gt;
&lt;p&gt;If you are looking for future green power, you&#039;ve found it. This is the ultimate renewable energy system, don&#039;t look any further, we are the most attractive solution and the most productive. Check out our triple converting Solar trees section to learn more about how this triple conversion will solve your energy problems, Solar Botanic trees and shrubs are so much more.&lt;/p&gt;
&lt;p&gt;Our growth is based on a vision of creating unique world-class products by adopting the best aspects for light, thermal and wind energy conversions from around the globe, which is why Solar Botanic will expand through every corner of the globe introducing an efficient and aesthetic solution for every culture, climate and ecosystem.&lt;/p&gt;
&lt;p&gt;Our products come with a guaranteed international quality control and assurance specification.&lt;/p&gt;
&lt;p&gt;------&lt;br /&gt;
Sun, wind, water, earth and life touch our living senses immediately always, everywhere and without any intervention of reason. They simply are there in their unmatched variety, moving us, our moods, memories, imaginations, intensions and plans.&lt;/p&gt;
&lt;p&gt;To capitalize on the wealth of designs and processes found in nature, engineering and technology gave us the ingredients, creative thinking, and unique solutions made it possible to bring all this together into a natural looking leaf - the Nanoleaf.&lt;/p&gt;
&lt;p&gt;To complete the tree for multi energy exploitation, the petiole twigs and branches are incorporated with Nano piezo-electric elements. A Nanoleaf is thin like a natural leaf, when outside forces, like the wind pushes the Nanoleaf back and forth, mechanical stresses appear in the petiole, twig and branches. When thousands of Nanoleaves flap back and forth due to wind, millions and millions of Pico watts are generated, the stronger the wind, the more energy is generated.&lt;/p&gt;
&lt;p&gt;Our Nanoleaves only reflect a small part of the sunlight that strikes them, mostly the green light, and the rest of the spectrum is efficiently converted into electricity.&lt;br /&gt;
&lt;a href=&quot;http://www.solarbotanic.com/images/p4_2.jpg&quot; title=&quot;http://www.solarbotanic.com/images/p4_2.jpg&quot;&gt;http://www.solarbotanic.com/images/p4_2.jpg&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Besides converting the visible spectrum of light, our Nanoleaves also convert the invisible light, known as infrared light or radiation, we can&#039;t see it, but we can feel it - it&#039;s warm - that&#039;s why we call it radiation. Due to the unique combination of photovoltaic and thermovoltaic in our Nanoleaves it converts this thermal radiation into electricity, even hours after the sun has set.&lt;/p&gt;
&lt;p&gt;The more wind there is,the more Nanoleaves are moved. Wind that is moving thousands of Nanoleaves in a tree canopy are causing mechanical strain in the petiole, twigs and branches. Nano piezo-electric elements incorporated in the petiole twigs and branches are the tiny Nano piezo-electric elements that will generate millions and millions of Pico watts as these thousands of Nanoleaves flap back and forth due to wind. The stronger the wind, the higher the &quot;flap&quot; frequency, and therefore the larger the watts generated in the petiole, twigs and branches.&lt;br /&gt;
&lt;a href=&quot;http://www.solarbotanic.com/images/p4_1.jpg&quot; title=&quot;http://www.solarbotanic.com/images/p4_1.jpg&quot;&gt;http://www.solarbotanic.com/images/p4_1.jpg&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;With the progress in nano technology, the photovoltaic, thermovoltaic and piezo electric materials are becoming more efficient and combined in one system it will give our products more efficiency and we believe that soon, Solar Botanic will be a mainstream green energy provider, more reliable/cheaper and above all better looking.&lt;br /&gt;

 <title>Next Generation Bone Void Filler</title>
 <link>http://www.nanovip.com/node/53867</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Pioneer&#039;s First In-House Biologic Product to Debut at NASS&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Pioneer Surgical Technology, Inc. today announced the U.S. market release of their FortrOss bone graft substitute. The novel biologic will make its public debut at the 23rd Annual Meeting of the North American Spine Society (NASS) in Toronto, Canada. The FortrOss bone void filler, utilizing the power of nanotechnology for orthopaedic applications, is a scaffold for the in-growth of new bone when superior bone regeneration is required.&lt;/p&gt;
&lt;p&gt;Pioneer&#039;s CEO and Chairman of the Board, Matthew N. Songer, MD, MBA says, &quot;The Pioneer Orthobiologics team has reached a huge milestone with the release of the FortrOss. This is the culmination of over 10 years work by each of the two companies, Encelle(TM) Inc. and Angstrom(TM) Medica, Inc. that were acquired by Pioneer in 2007.&quot;&lt;br /&gt;
The FortrOss bone void filler combines the nanotechnology of nanOss(TM) hydroxyapatite with the bone growth promotion of E-Matrix(TM) scaffold. The FortrOss bone void filler is the most advanced on the market. The FortrOss osteoconductive matrix utilizes Pioneer&#039;s nanOss(TM) technology and is designed to mimic the nanostructures inherent in bone tissue.&lt;/p&gt;
&lt;p&gt;According to Dr. Edward Ahn, Vice President of Biomaterials at Pioneer states, &quot;Because the nanOss hydroxyapatite in FortrOss resembles the size, shape, and chemistry of native bone, bone tissue has a great affinity for nanOss and recognizes it as native tissue. This mimicry of native bone makes nanOss superior to other calcium phosphates on the market.&quot;&lt;br /&gt;
The combined nanotechnology-based osteoconduction and osteopromotive E- Matrix scaffold of FortrOss bone void filler positions Pioneer to impact significantly the dynamic field of bone repair.&lt;/p&gt;
&lt;p&gt;About Pioneer Surgical Technology&lt;br /&gt;

The emerging science that captured the media’s imagination about a decade ago with visions of supercomputers mounted in wristwatches and X-ray machines that hang from your doctor’s neck like a stethoscope ... and then scuttled back into the laboratory for a prolonged reality check?&lt;/p&gt;
&lt;p&gt;Well there’s finally something that nanotechnology can do for you — or, better, help you do for yourself, at your own home, with your own hands, at a price you can afford. While many of nanotech’s flashy gadgets and futuristic technologies remain in the research and development phase, a more mundane but — in this era of global climate change and energy shortages — perhaps more important product has emerged from the labs.&lt;/p&gt;
&lt;p&gt;That product is called “Nansulate,” a paint-on insulation with an extremely low thermal conductivity value. Patented and manufactured by Industrial Nanotech Inc., Nansulate suspends specially engineered microscopic particles with nano-scale internal architecture in an acrylic resin, which is in turn suspended in water (similar to thick, acrylic-based paint). Nansulate is designed to be nontoxic and environmentally friendly, and because the microparticles are water-repellant, it is also an effective mold and rust inhibitor.&lt;/p&gt;
&lt;p&gt;Developed initially for industrial applications such as insulating steam pipes and boilers, Nansulate found its way into the residential market by popular demand. According to Francesca Crolley, Industrial Nanotech’s vice president of operations and marketing, many people who learned about Nansulate through their jobs at industrial facilities inquired about the possibility of using it at home.&lt;/p&gt;
&lt;p&gt;In response, the company developed a residential version of Nansulate that can be applied with a brush, paint roller or sprayer and cleans up with water. The product is designed for use on walls (usually interior), hot water pipes, water heaters and even skylights and glass block. (The clear product leaves a slightly cloudy film on windows.) Nansulate can be applied over existing paint, and it can be painted over once it has cured (a 30-day curing time is recommended).&lt;/p&gt;
&lt;p&gt;Paint-on insulation can address the pervasive problem of uninsulated walls in older homes. While it is easy, in most cases, to put conventional insulation above ceilings and under floors, sealed walls must be opened and resealed or have insulation pumped through holes, which must then be patched. The cost/benefit ratio of insulating existing walls is therefore marginal, and homeowners often skip doing it.&lt;/p&gt;
&lt;p&gt;At its current price of $66 per gallon (covering about 150 sq. ft.), Nansulate offers a highly economical solution to insulating existing walls. But while you’re at it, why not paint your ceiling, too, and conserve more energy — even if your attic is insulated.&lt;/p&gt;
&lt;p&gt;How much energy can you save with Nansulate? Unfortunately, there is no data that directly compares the performance of Nansulate with that of conventional insulations. That’s because conventional insulations inhibit heat conduction as a function of their thickness (R-value per inch), whereas Nansulate is a non-conductor (insulator) that blocks both conductive and radiant heat flow even when it’s paper thin.&lt;/p&gt;
&lt;p&gt;There is, however, a great deal of information about Nansulate’s performance based on real-life tests in industrial and residential settings. Factory owners have reported savings of 20 percent or more on their overall energy costs. Home energy savings of 20 to 40 percent are reported in testimonials on the Industrial Nanotech Web site.&lt;/p&gt;
&lt;p&gt;I contacted the author of one of those testimonials, Kevin Lagario, who has used Nansulate at his home and in his green technology business in California (he has no financial ties to Industrial Nanotech). He had applied three coats of Nansulate to each side of a plywood shed housing hot water tanks, added some thin foil-and-bubble-wrap insulation and measured an inside temperature of 120 degrees when it was 60 degrees outside.&lt;/p&gt;
&lt;p&gt;Although there are other paint-on insulations on the market, they are mostly ceramic-based and used on roofs and exterior walls.&lt;/p&gt;
&lt;p&gt;Testing Nansulate in one or two rooms could show you if it is the appropriate nanotechnology for your ecological house.&lt;/p&gt;

 <title>Alternative to fossil fuels from nanotechnology</title>
 <link>http://www.nanovip.com/node/53864</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Nanotechnologies can be used to develop sustainable energy systems while reducing the harmful effects of fossil fuels as they are gradually phased out over the next century.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;This optimistic scenario is coming closer to reality as new technologies such as biomimetics and Dye Sensitised Solar Cells (DSCs) emerge with great promise for capturing or storing solar energy, and as nanocatalysis develops efficient catalysts for energy-saving industrial processes Europe is ready to accelerate development of these technologies, as delegates heard at a recent conference, Nanotechnology for Sustainable Energy, organised by the European Science Foundation (ESF) &lt;/p&gt;
&lt;p&gt;The conference focused on solar rather than other sustainable energy sources such as wind, because that is where nanotechnology is most applicable and also because solar energy conversion holds the greatest promise as a long-term replacement of fossil fuels.&lt;/p&gt;
&lt;p&gt;Solar energy can be harvested directly to generate electricity or to yield fuels such as hydrogen for use in engines.&lt;/p&gt;
&lt;p&gt;Such fuels can also in turn be used indirectly to generate electricity in conventional power stations. &lt;/p&gt;
&lt;p&gt;&#039;The potential of solar power is much, much larger in absolute numbers than that of wind,&#039; said Professor Bengt Kasemo from Chalmers University of Technology and the chair of the ESF conference.&lt;/p&gt;
&lt;p&gt;However, like wind, the potential of solar power generation varies greatly across time and geography, being confined to the daytime and less suitable for regions in higher latitudes, such as Scandinavia and Siberia.&lt;/p&gt;
&lt;p&gt;For this reason there is growing interest in the idea of a global electricity grid according to Kasemo.&lt;/p&gt;
&lt;p&gt;&#039;If solar energy is harvested where it is most abundant, and distributed on a global net (easy to say - and a hard but not impossible task to do) it will be enough to replace a large fraction of today&#039;s fossil-based electricity generation,&#039; said Kasemo.&lt;/p&gt;
&lt;p&gt;&#039;It would also solve the day/night problem and therefore reduce storage needs because the sun always shines somewhere.&#039; In the immediate future, solid state technologies based on silicon are likely to predominate the production (manufacture) of solar cells, but DSC and other &#039;runner ups&#039; are likely to lower costs in the long term, using cheaper semiconductor materials to produce robust flexible sheets strong enough to resist buffeting from hail for example.&lt;/p&gt;
&lt;p&gt;Although less efficient than the very best silicon or thin film cells using current technology, their better price/performance has led the European Union to predict that DSCs will be a significant contributor to renewable energy production in Europe by 2020.&lt;/p&gt;
&lt;p&gt;The DSC was invented by Michael Gratzel, one of the speakers and vice chair at the ESF conference.&lt;/p&gt;
&lt;p&gt;The key point to emerge from the ESF conference, though, is that there will be growing choice and competition between emerging nanotechnology-based solar conversion technologies.&lt;/p&gt;
&lt;p&gt;&#039;I think the important fact is that there is strong competition and that installed solar power is growing very rapidly, albeit from a small base,&#039; said Kasemo.&lt;/p&gt;
&lt;p&gt;&#039;This will push prices down and make solar electricity more and more competitive.&#039; Some of the most exciting of these alternatives lie in the field of biomimetics, which involves mimicking processes that have been perfected in biological organisms through eons of evolution.&lt;/p&gt;
&lt;p&gt;Plants and a class of bacteria, cyanobacteria, have evolved photosynthesis, involving the harvesting of light and the splitting of water into electrons and protons to provide a stream of energy that in turn produces the key molecules of life.&lt;/p&gt;
&lt;p&gt;Photosynthesis can potentially be harnessed either in genetically-engineered organisms, or completely artificial human-made systems that mimic the processes, to produce carbon-free fuels such as hydrogen.&lt;/p&gt;
&lt;p&gt;Alternatively, photosynthesis could be tweaked to produce fuels such as alcohol or even hydrocarbons that do contain carbon molecules but recycle them from the atmosphere and therefore make no net contribution to carbon dioxide levels above ground.&lt;/p&gt;
&lt;p&gt;Biomimetics could also solve the longstanding problem of how to store large amounts of electricity efficiently.&lt;/p&gt;
&lt;p&gt;This could finally open the floodgates for electrically-powered vehicles by enabling them at last to match the performance and range of their petrol or diesel-based counterparts.&lt;/p&gt;
&lt;p&gt;One highlight of the ESF conference was a presentation by Angela Belcher, who played a major role in pioneering nanowires made from viruses at the Massachusetts Institute of Technology (MIT) in the US.&lt;/p&gt;
&lt;p&gt;Bizarre as it sounds, there is a type of virus that infects E.coli bacteria (a bacteriophage) capable of coating itself in electrically-conducting materials such as gold.&lt;/p&gt;
&lt;p&gt;This can be used to build compact high capacity batteries, with the added advantage that it can potentially assemble itself, exploiting the natural replicating ability of the virus.&lt;/p&gt;
&lt;p&gt;The key to the high capacity in small space lies in the microscopic size of the nanowires constructed by the viruses - this means that a greater surface area of charge carrying capacity can be packed into a given volume.&lt;/p&gt;
&lt;p&gt;However, commercial realisation of biomimetic and other emerging technologies lies far in the future.&lt;/p&gt;
&lt;p&gt;Meanwhile, as delegates heard from several speakers at the ESF conference, nanotechnology has an important contribution to make, improving the efficiency of existing energy-generating systems during the transition from fossil fuels.&lt;/p&gt;
&lt;p&gt;For example, Robert Schlogl outlined how nanoscale catalysts can be used to improve the efficiency of engines or systems consuming fossil fuels.&lt;/p&gt;
&lt;p&gt;Inspired by such presentations, delegates at the conference were unanimous in calling for a follow up.&lt;/p&gt;
&lt;p&gt;&#039;The conference was regarded as a real success and a new proposal for a conference in 2010 (chaired by Gratzel) will soon be submitted,&#039; said Kasemo.&lt;/p&gt;
&lt;/div&gt;

 <title>Researchers Write Protein Nanoarrays Using A Fountain Pen And Electric Fields</title>
 <link>http://www.nanovip.com/node/53863</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Nanotechnology offers unique opportunities to advance the life sciences by facilitating the delivery, manipulation and observation of biological materials with unprecedented resolution.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Nanotechnology offers unique opportunities to advance the life sciences by facilitating the delivery, manipulation and observation of biological materials with unprecedented resolution. The ability to pattern nanoscale arrays of biological material assists studies of genomics, proteomics and cell adhesion, and may be applied to achieve increased sensitivity in drug screening and disease detection, even when sample volumes are severely limited.&lt;/p&gt;
&lt;p&gt;Unfortunately, most tools capable of patterning with such tiny resolution were developed for the silicon microelectronics industry and cannot be used for soft and relatively sensitive biomaterials such as DNA and proteins.&lt;/p&gt;
&lt;p&gt;Now a team of researchers at Northwestern University has demonstrated the ability to rapidly write nanoscale protein arrays using a tool they call the nanofountain probe (NFP).&lt;/p&gt;
&lt;p&gt;&quot;The NFP works much like a fountain pen, only on a much smaller scale, and in this case, the ink is the protein solution,&quot; said Horacio Espinosa, head of the research team and professor of mechanical engineering in the McCormick School of Engineering and Applied Science at Northwestern.&lt;/p&gt;
&lt;p&gt;The results, which will be published online the week of Oct. 13 in the Proceedings of the National Academy of Sciences (PNAS), include demonstrations of sub-100-nanometer protein dots and sub-200-nanometer line arrays written using the NFP at rates as high as 80 microns/second.&lt;/p&gt;
&lt;p&gt;Each nanofountain probe chip has a set of ink reservoirs that hold the solution to be patterned. Like a fountain pen, the ink is transported to sharp writing probes through a series of microchannels and deposited on the substrate in liquid form.&lt;/p&gt;
&lt;p&gt;&quot;This is important for a number of reasons,&quot; said Owen Loh, a graduate student at Northwestern who co-authored the paper with fellow student Andrea Ho. &quot;By maintaining the sensitive proteins in a liquid buffer, their biological function is less likely to be affected. This also means we can write for extended periods over large areas without replenishing the ink.&quot;&lt;/p&gt;
&lt;p&gt;Earlier demonstrations of the NFP by the Northwestern team included directly writing organic and inorganic materials on a number of different substrates. These included suspensions of gold nanoparticles, thiols and DNA patterned on metallic- and silicon-based substrates.&lt;/p&gt;
&lt;p&gt;In the case of protein deposition, the team found that by applying an electrical field between the nanofountain probe and substrate, they could control the transport of protein to the substrate. Without the use of electric fields, protein deposition was relatively slow and sporadic. However, with proper electrical bias, protein dot and line arrays could be deposited at extremely high rates.&lt;/p&gt;
&lt;p&gt;&quot;The use of electric fields allows an additional degree of control,&quot; Espinosa said. &quot;We were able to create dot and line arrays with a combination of speed and resolution not possible using other techniques.&quot;&lt;/p&gt;
&lt;p&gt;Positively charged proteins can be maintained inside the fountain probe by applying a negative potential to the NFP reservoirs with respect to a substrate. Reversing the applied potential then allows protein molecules to be deposited at a desired site.&lt;/p&gt;
&lt;p&gt;To maximize the patterning resolution and efficiency, the team relied on computational models of the deposition process. &quot;By modeling the ink flow within the probe tip, we were able to get a sense of what conditions would yield optimal patterns,&quot; says Jee Rim, a postdoctoral researcher at Northwestern.&lt;/p&gt;
&lt;p&gt;Espinosa collaborated closely with Neelesh Patankar, associate professor of mechanical engineering at Northwestern, and Punit Kohli, assistant professor of chemistry and biochemistry at Southern Illinois University, Carbondale.&lt;/p&gt;
&lt;p&gt;&quot;We are very excited by these results,&quot; said Espinosa. &quot;This technique is very broadly applicable, and we are pursuing it on a number of fronts.&quot; These include single-cell biological studies and direct-write fabrication of large-scale arrays of nanoelectrical and nanoelectromechanical devices.&lt;/p&gt;
&lt;p&gt;&quot;The fact that we can batch fabricate large arrays of these fountain probes means we can directly write large numbers of features in parallel,&quot; added Espinosa. &quot;The demonstration of rapid protein deposition rates further supports our efforts in producing a large-scale nanomanufacturing tool.&quot;&lt;/p&gt;
&lt;p&gt;The paper in the Proceedings of the National Academy of Sciences was authored by Loh, Ho, Rim, Patankar, Kohli and Espinosa.&lt;/p&gt;
&lt;/div&gt;

 <title>Nanotechnology could kill small farmers</title>
 <link>http://www.nanovip.com/node/53862</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Despite the many benefits of nanotechnology on electronics, medicines, and foods, a non-government organization is now seeing the pains such technology could bring.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;In the field of nano agriculture, it is believed that it could hurt small-scale farmers who supply the world with small-scale raw materials.&lt;/p&gt;
&lt;p&gt;ETC Group or the Action Group on Erosion, Technology, and Concentration executive director Pat Mooney, in his briefing with members of the Davao media, Mooney shared the impacts it could cause the world especially those in the Third World.&lt;/p&gt;
&lt;p&gt;With the advent of nanotechnology or the manipulation of matter at the level of atoms and molecules, ETC has seen how such technology would change every step of the food chain as well as the people involved in the process.&lt;/p&gt;
&lt;p&gt;Mooney explained that the highly-developed countries lead the world market, however, they still recognize and get raw materials from other countries like the Third World.&lt;/p&gt;
&lt;p&gt;But with nanotechnology, where the power and manipulation is at the hands of the scientifically-advanced, the group is seeing a rapid change in the world&#039;s economy.&lt;/p&gt;
&lt;p&gt;The expert disclosed Kraft Foods&#039; move of coming up with a product that would automatically change clear water to any kind of drink like soda, coffee, or tea in just a matter of click on the microwave machine.&lt;/p&gt;
&lt;p&gt;&quot;This product will soon flood the grocery stores and would eventually kill all other beverage products as well as the farmers who provide the raw materials,&quot; he said.&lt;/p&gt;
&lt;p&gt;ETC is now mindful on the world&#039;s $3 trillion food retail market, agricultural export markets valued at $544 billion, and the livelihood of some 2.6 billion farming people.&lt;/p&gt;
&lt;p&gt;It is believed that the poor and marginalized are seldom in a position to foresee or adjust quickly to abrupt economic changes.&lt;/p&gt;
&lt;p&gt;&quot;Among the most vulnerable will be small-scale farmers and agricultural workers who produce raw commodity exports in the developing world.&lt;/p&gt;
&lt;p&gt;Mooney visited Philippines to talk to different sectors in the community and share vital information needed by the public to prepare them for the big changes in the world market.&lt;/p&gt;
&lt;p&gt;In the field of nano-foods, huge companies have started to invest on their research department to explore nano-scales by enhancing the taste and adding health benefits without having to add production cost.&lt;/p&gt;
&lt;p&gt;An example cited is a beverage that claims no sugar in it but actually adds an enzyme that is capable in blocking some bitter taste buds.&lt;/p&gt;
&lt;p&gt;He urged the government to share these information to the Filipino people and let them start preparing for the coming changes.&lt;/p&gt;
&lt;p&gt;&quot;The technology is moving so fast and yet our policymakers are so left behind. The people deserve to know all these,&quot; he said.&lt;/p&gt;
&lt;p&gt;The world now estimates about 800 manufacturer-identified consumer products that use nanotechnology. These are already being sold in the world market in the absence of regulation and monitoring.&lt;/p&gt;
&lt;p&gt;Data showed that the nanotech market for food and processing alone is estimated to be in excess of $2 billion and projected to surge to more than $20 billion by 2010.&lt;/p&gt;

 <title>Mesothelioma Lawsuit Filed by California Woman</title>

  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Threat of Mesothelioma and Nanotechnology Causes Concern for Insurance Company&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Over the course of the past year, new reports have revealed the asbestos-like qualities of carbon nanotubes and their potential ability to cause mesothelioma (a cancer almost exclusively caused by asbestos exposure).&lt;/p&gt;
&lt;p&gt;However, the research is by no means conclusive. One insurance company, Continental Western Insurance Group, has responded by saying they will exclude coverage of nanotechnology starting in November. The company’s reason for this is due to the “Unknown and unknowable risks created by the products and processes that involved nanotubes.”&lt;/p&gt;
&lt;p&gt;The statement from the insurance company says, “Reports have raised concerns regarding health risks from workers that may be inhaling carbon nanotubes during the manufacture of certain products. The carbon nanotubes resemble asbestos fibers in appearance, raising the concern that they may cause illness similar to that linked to asbestos.”&lt;/p&gt;
&lt;p&gt;CWG plans to attach a nanotube exclusion to all policy issues for business owners, motor carriers, and other various insurance products. The company has also called for further research into the possible long-term consequences of being exposed to nanotubes.&lt;/p&gt;
&lt;p&gt;The result of current research is far from being conclusive. One study showed nanotubes caused lesions similar to those caused by asbestos, but involved the implantation of nanotube fibers into experimental rats. Another study suggested that only carbon nanotubes of a particular long, thin, shape have the potential to cause malignant mesothelioma.&lt;/p&gt;
&lt;p&gt;Some believe CWG is just trying to save money by using the word “asbestos” as a trigger-word and relating it to carbon nanotubes. Insurance companies in the past have paid out big money due to asbestos-related claims concerning asbestosis, lung cancer, and pleural mesothelioma.&lt;/p&gt;
&lt;p&gt;The EPA, as well as other environmental groups, are concerned about the possible consequences of the use of nanotechnology. However, Vicki Colvin, director of the National Science Foundation-funded Center for Biological and Environmental Nanotechnology, says the potential benefits of carbon nanotubes are simply too powerful to ignore.&lt;/p&gt;

  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Iran successfully reached the first grade in the nanotechnology activities among the Islamic countries in 2008.&lt;/p&gt;
&lt;/div&gt;

  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;“The purpose of development of nano is to create wealth and increase the life quality,” said the vice-secretary of the special headquarters of nanotechnology.&lt;/p&gt;
&lt;p&gt;“Iran should be able to reach the 15th grade in this technology by the next 10 years and should directly earn 10 billion Dollars,” added Saaber Mirzaaei.&lt;/p&gt;
&lt;p&gt;“Creating electron-based microscopes which are of the complicated measuring systems are of the most successful achievements were reached by nanotechnology,” he continued.&lt;/p&gt;
&lt;p&gt;“A special particular fund has devoted for this in order to support the active people of the field,” he affirmed.&lt;/p&gt;
&lt;p&gt;“In the year 2000, Iran was the world’s 60th country and Islamic countries’ 6th and is 20th in the world and first among the Islamic countries, in 2008,” stated Mirzaaei.&lt;/p&gt;
&lt;p&gt;A festival for exhibiting abilities of nanotechnology has opened today in the Center for Mental Culture of Children and Youth, located in the street “Hejaab” of Tehran and will be continued until the 24th of the month Mehr.\&lt;/p&gt;

          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Dr. Hermann E. Gaub, head of the Biophysics and Molecular Materials Group in the Physics Department at the Ludwig-Maximilians-University (LMU) of Munich, together with Elias Puchner and colleagues from the university&#039;s Center for Nanoscience and the Center for Integrated Protein Science Munich, combined the precision of atomic force microsccopy with the selectivity of DNA interaction to create freely programmable nanopatterns of DNA-oligomers on a surface and in aqueous environment.&lt;/p&gt;
&lt;p&gt;What the LMU researchers did was create a DNA scaffold by picking biotin bearing DNA oligomers with an AFM tip and depositing them, one by one, in a desired pattern on a surface, basically creating a pattern of attachment points for fluorescent semiconductor nanoparticles conjugated with streptavidin. The small bacterial protein streptavidin is commonly used for the detection of various biomolecules and it binds with high affinity to the vitamin biotin. The strong streptavidin-biotin bond can be used to attach various biomolecules to one another or onto a solid support.&lt;/p&gt;
&lt;p&gt;When the sample with the DNA scaffold is incubated with a solution of fluorescent nanoparticles, a rapid self-assembly process of these particles on the predefined scaffold takes place.&lt;/p&gt;

 <title>Cal State Northridge has come a long way in 50 years</title>
 <link>http://www.nanovip.com/node/53858</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;NORTHRIDGE - In a basement lab at California State University, Northridge, students don astronautlike white suits to study the tiniest of molecules.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Having a nanotechnology lab boasting $100,000 microscopes represents a giant leap for a university that 50 years ago sprouted amid orange groves and squash fields.&lt;/p&gt;
&lt;p&gt;&quot;It was all temporary buildings then, maybe 2,000 people on the entire campus,&quot; said Vince Barabba, a member of the school&#039;s founding class. &quot;It was a close-knit environment where students and faculty came together. It was a rare opportunity to start a college with a clean slate.&quot;&lt;/p&gt;
&lt;p&gt;Now, as the school celebrates its 50th anniversary, it is also engaging in its largest construction boom ever, including the addition of a $100 million performing arts center. And its enrollment has grown more than tenfold since those early days, reaching a record 36,600 this fall.&lt;/p&gt;
&lt;p&gt;&quot;We have had about 190,000 alums in 50 years. We are educating more teachers than the entire UC system and we are one of the largest employers in the San Fernando Valley, employing about 4,000 people,&quot; said CSUN President Jolene Koester. &quot;This university has always been focused on this region.&quot;&lt;/p&gt;
&lt;p&gt;But in many ways, the Valley&#039;s only public university is still a campus trying to find its way.&lt;/p&gt;
&lt;p&gt;Koester&#039;s plans for the college include becoming a nationally recognized institution.&lt;/p&gt;
&lt;p&gt;&quot;Forever there have been conflicting visions of what this college should become,&quot; said John &lt;/p&gt;
&lt;p&gt;Broesamle, a former CSUN history professor and author of the book &quot;Suddenly a Giant: A History of California State University, Northridge.&quot;&lt;/p&gt;
&lt;p&gt;From its inception, founding members of the school saw CSUN as competitive with UCLA and the University of Southern California, he said.&lt;/p&gt;
&lt;p&gt;A satellite version of the school started in 1955 out of rented space in San Fernando High School. The first president&#039;s office was out of his car&#039;s front seat, Broesamle said.&lt;/p&gt;
&lt;p&gt;CSUN&#039;s humble start, coupled with its suburban location, led many to think of the school as a small, semirural liberal arts college.&lt;/p&gt;
&lt;p&gt;&quot;But the small college in a rural environment was not sustainable,&quot; Broesamle said.&lt;/p&gt;
&lt;p&gt;As the North Valley&#039;s fields gave way to tract homes, apartments and retail stores after World War II, CSUN also evolved.&lt;/p&gt;
&lt;p&gt;The college began to plow its green space to make room for new classrooms, a library and student housing, and students began to ask for change inside the classroom.&lt;/p&gt;
&lt;p&gt;By 1968, it felt its first round of growing pains when African-American and Chicano students, encouraged by the nation&#039;s ongoing civil rights movement, started protesting the school&#039;s lack of minorities.&lt;/p&gt;
&lt;p&gt;Tensions reached a boiling point Nov. 4 that year when members of CSUN&#039;s Black Student Union accused a volunteer football coach of discrimination against a black football player.&lt;/p&gt;
&lt;p&gt;They took over the fifth floor of the campus administration building. More than 100 LAPD officers were called in, and it all ended peacefully.&lt;/p&gt;
&lt;p&gt;&quot;It&#039;s ironic that the university that always aspired to national recognition was first recognized nationally as a fountainhead of student protests,&quot; Broesamle said.&lt;/p&gt;
&lt;p&gt;As a result, CSUN created Pan-African Studies and Chicano/Chicana Studies departments as part of the agreement reached between student leaders and administrators.&lt;/p&gt;
&lt;p&gt;Rudy Acuna, the founding faculty member for the Chicano/Chicana Studies Department, said getting the programs off the ground was difficult.&lt;/p&gt;
&lt;p&gt;&quot;Those first three years were hell,&quot; Acuna said. &quot;Police were engaged in racial profiling. Originally even the Spanish Department objected to our program. They thought the programs would go away, but we kept pushing.&quot;&lt;/p&gt;
&lt;p&gt;Today, the program serves 5,000 students a semester and is one of the largest of its kind in the country.&lt;/p&gt;
&lt;p&gt;In 1994, CSUN was faced with a different kind of movement when the 6.7-magnitude Northridge Earthquake left most of the campus in rubble, with more than $300 million worth of damage.&lt;/p&gt;
&lt;p&gt;It reopened weeks later in temporary bungalows with a lower enrollment, but 14 years later it has fully recovered.&lt;/p&gt;
&lt;p&gt;Looking ahead, the college faces many challenges. As the Valley continues to diversify, CSUN has to adjust its programs to its changing student body.&lt;/p&gt;
&lt;p&gt;Tom Spencer-Walters, chairman of the Pan-African Studies Department, said while minority programs have flourished - now including departments for women&#039;s studies, Asian-American studies, Central-American studies and most recently queer studies - the recruitment of minority faculty continues to be an issue.&lt;/p&gt;
&lt;p&gt;&quot;If ethnic studies were not on the campus, we would not be meeting our diversity objectives with faculty,&quot; Spencer-Walters said.&lt;/p&gt;
&lt;p&gt;The current state budget crunch is also a growing issue for a college where more than half of the students are on financial aid.&lt;/p&gt;
&lt;p&gt;&quot;When I registered in the fall of 2005 my fees, with everything included, were about $1,500. ... Now they are almost $2,000,&quot; said Raul Marquez, 21, a 21 year-old senior majoring in kinesiology.&lt;/p&gt;
&lt;p&gt;&quot;I know we are getting a new science building, parking structure and a performance hall, but it seems like an inordinate amount of money in a small time frame. I hope CSUN continues to think about the college as a center for education, not a business.&quot;&lt;/p&gt;
&lt;p&gt;For many, like nanotechnology professor Henk Postma, the mission remains clear. A Caltech doctoral graduate, he could have taught students the intricacies of the nanometer at pretty much any college.&lt;/p&gt;
&lt;p&gt;But the Netherlands native said CSUN held a special attraction for him.&lt;/p&gt;
&lt;p&gt;&quot;I like the fact that we are teaching these types of students who typically don&#039;t go to research institutions - first-generation students,&quot; he said. &quot;It&#039;s so important to engage these types of students.&quot;&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

 <title>Secrets of superbug-busting antibiotic revealed by UCL researchers </title>
 <link>http://www.nanovip.com/node/53857</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;This week Nature Nanotechnology journal reveals how scientists from the London Centre for Nanotechnology (LCN) at UCL are using a novel nanomechanical approach to investigate the workings of vancomycin&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;This week Nature Nanotechnology journal reveals how scientists from the London Centre for Nanotechnology (LCN) at UCL are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat so-called ‘superbugs’, such as MRSA.&lt;/p&gt;
&lt;p&gt;The researchers, led by Dr Rachel McKendry and Professor Gabriel Aeppli, developed ultra-sensitive probes capable of providing new insight into how antibiotics work, paving the way for the development of more effective new drugs.&lt;/p&gt;
&lt;p&gt;“There has been an alarming growth in antibiotic-resistant hospital superbugs such as MRSA and vancomycin-resistant Enterococci (VRE),” said Dr McKendry. “This is a major global health problem and is driving the development of new technologies to investigate antibiotics and how they work.&lt;/p&gt;
&lt;p&gt;“The cell wall of these bugs is weakened by the antibiotic, ultimately killing the bacteria,” she continued.&lt;/p&gt;
&lt;p&gt;“Our research on cantilever sensors – tiny levers no wider than a human hair – suggests that the cell wall is disrupted by a combination of a local antibiotic and a polymer known as a mucopeptide binding together, and the spatial mechanical connectivity of these events.&lt;/p&gt;
&lt;p&gt;“Investigating both these binding and mechanical influences on the cells’ structure could lead to the development of more powerful and effective antibiotics in future.”&lt;/p&gt;
&lt;p&gt;During the study Dr McKendry, Joseph Ndieyira, Moyu Watari and co-workers used these cantilever arrays to examine the process that ordinarily takes place in the body when vancomycin binds itself to the surface of the bacteria.&lt;/p&gt;
&lt;p&gt;They coated the cantilever array with polymers known as mucopeptides from bacterial cell walls and found that, as the antibiotic attaches itself it generates a surface stress on the bacteria, which can be detected by a tiny bending of the cantilever sensors.&lt;/p&gt;
&lt;p&gt;The team suggests that this stress contributes to the disruption of the cell walls and the breakdown of the bacteria.&lt;/p&gt;
&lt;p&gt;The interdisciplinary team went on to compare how vancomycin interacts with both non-resistant and resistant strains of bacteria. The ‘superbugs’ are resistant to antibiotics because of a simple mutation that deletes a single hydrogen bond from the structure of their cell walls.&lt;/p&gt;
&lt;p&gt;This small change makes it approximately 1,000 times harder for the antibiotic to attach itself to the bug, leaving it much less able to disrupt the cells’ structure, and therefore therapeutically ineffective. &lt;/p&gt;
&lt;p&gt;“This work at the LCN demonstrates the effectiveness of silicon-based cantilevers for drug screening applications,” says Professor Gabriel Aeppli, Director of the LCN.&lt;/p&gt;
&lt;p&gt;“According to the Health Protection Agency, during 2007 there were around 7,000 cases of MRSA and more than a thousand cases of VRE in England alone. In recent decades the introduction of new antibiotics has slowed to a trickle but without effective new drugs the number of these fatal infections will increase.”&lt;/p&gt;
&lt;p&gt;The research was funded by the EPSRC (Speculative Engineering Programme), the IRC in Nanotechnology (Cambridge, UCL and Bristol), the Royal Society and the BBSRC.&lt;/p&gt;

 <title>&#039;Nanotech search&#039; for antibiotics </title>
 <link>http://www.nanovip.com/node/53856</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;UK researchers are using microscopic &quot;nanoprobes&quot; to find new drugs to tackle antibiotic resistance.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;The tiny ultra-sensitive probes can measure how well a drug binds to bacteria and its ability to weaken and destroy the bug.&lt;/p&gt;
&lt;p&gt;The researchers tested the silicon-based technology on vancomycin, one of the few remaining antibiotics against infections such as MRSA&lt;/p&gt;
&lt;p&gt;The initial results are published in Nature Nanotechnology.&lt;/p&gt;
&lt;p&gt;It is the first time this type of nanotechnology has been used in screening for new drugs.&lt;br /&gt;
The probes are no wider than a human hair - which may seem big by nanotechnology standards - but they are able to detect minute changes at the molecular level.&lt;/p&gt;
&lt;p&gt;Antibiotics such as vancomycin bind to the bacterial cell wall, disrupting it and causing the bacteria to break down.&lt;/p&gt;
&lt;p&gt;When bacteria become resistant, small changes occur in the structure of their cell wall making it far harder for the antibiotic to latch on and weaken the structure of the cell.&lt;/p&gt;
&lt;p&gt;&#039;Surface stress&#039;&lt;/p&gt;
&lt;p&gt;The researchers from the London Centre for Nanotechnology coated a series of the nanoprobes with the proteins that make up bacterial cell walls.&lt;/p&gt;
&lt;p&gt;Like a tiny row of diving boards, the probes bend in response to the &quot;surface stress&quot; that occurs when the antibiotic binds to the cell.&lt;/p&gt;
&lt;p&gt;The system was able to detect that it is 1,000 times harder for vancomycin to attach to resistant bacteria than to non-resistant bacteria.&lt;/p&gt;
&lt;p&gt;They are now screening other potential antibiotics with the goal of finding a drug that is able to bind strongly to resistant bacteria and cause substantial structural weaknesses to the cell wall.&lt;/p&gt;
&lt;p&gt;Study leader Dr Rachel McKendry said: &quot;There has been an alarming growth in antibiotic-resistant hospital &#039;superbugs&#039; such as MRSA and vancomycin resistant Enterococci (VRE).&lt;/p&gt;
&lt;p&gt;&quot;This a major global health problem and is driving the development of new technologies to investigate antibiotics and how they work.&quot;&lt;/p&gt;
&lt;p&gt;She added that different drugs caused different structural weaknesses in the cell wall - some of which were more effective than others - and the nanotechnology they were using could help to pinpoint those that were likely to cause the most destruction.&lt;/p&gt;
&lt;p&gt;Professor Jeff Errington, director of the Institute for Cell and Molecular Biosciences at the University of Newcastle said the technology was very interesting and obviously highly sensitive.&lt;/p&gt;
&lt;p&gt;But he said it did not solve the problem of finding new antibiotics to test in the first place.&lt;/p&gt;
&lt;p&gt;&quot;The bottleneck is in finding new molecules that kill bacteria by novel pathways,&quot; he said.&lt;/p&gt;
&lt;/div&gt;

 <title>Three reasons why a declining economy can be good for nanotechnology</title>
 <link>http://www.nanovip.com/node/53855</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;With the recent decline of the stock market, the reduction of lending, and the dearth of IPOs in 2008 things may look bleak for emerging technologies such as nanotech. But, while near term projections may look bad, in the long term economic decline could actually be extremely beneficial to technological developments involving nanomaterials. Here are three reasons why:&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;1.   Less resources force innovators to look for simpler more economical solutions.&lt;/p&gt;
&lt;p&gt;Most invention is incremental in nature and build upon decades of earlier developments. For example, the  techniques to manufacture integrated circuits have been developed over about 50 years and while the improvements in these techniques have been significant and have led to cheaper and more efficient electronics, the manufacturing cost and complexity have increased at a similar pace in accordance with Moore’s 2nd law. Semiconductor and electronics companies faced with a rapid decline in capital may be forced to look for dramatically different approaches to fabrication in order to stay in business. It is very likely that nanomaterials and nanolithographic techniques may play a key role in such new fabrication.   &lt;/p&gt;
&lt;p&gt;2.   Nanotech. start-ups will be forced to focus on applications rather than on pure materials.&lt;/p&gt;
&lt;p&gt;With less venture capital to go around it is likely that investment will go to those companies having business plans with clearly identified markets and applications. Start-ups lacking such direction will be forced to reprioritize or go out of business. While harsh in the short term this could be a good thing in the long run leading to new market creation.&lt;/p&gt;
&lt;p&gt;3.   The fall of the stock market will weaken older, public companies allowing newer, non-public companies a competitive advantage.&lt;/p&gt;
&lt;p&gt;Companies not relying on public stock have a strategic advantage and more freedom to operate than public companies. Meanwhile older, public companies which need to answer to shareholders will be forced to compromise and may be more willing to deal with newer companies offering cost-cutting solutions offered by nanomaterials. In addition, in good economic times, distributors may have no desire to work with new companies offering cost reduced products due to longstanding relationships with more established companies. However, when the economy declines to a sufficient degree the distributors may reprioritize and give more weight to cost reduction than customer relationships offering a window of opportunity to newer competitors.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

 <title>Sensitive nanowire disease detectors created</title>
 <link>http://www.nanovip.com/node/53854</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Yale scientists have created nanowire sensors coupled with simple microprocessor electronics that are both sensitive and specific enough to be used for point-of-care (POC) disease detection, according to a report in Nano Letters.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;The sensors use activation of immune cells by highly specific antigens - signatures of bacteria, viruses or cancer cells - as the detector. When T cells are activated, they produce acid, and generate a tiny current in the nanowire electronics, signaling the presence of a specific antigen. The system can detect as few as 200 activated cells.&lt;/p&gt;
&lt;p&gt;In earlier studies, these researchers demonstrated that the nanowires could detect generalized activation of this small number of T cells. The new report expands that work and shows the nanowires can identify activation from a single specific antigen even when there is substantial background &quot;noise&quot; from a general immune stimulation of other cells.&lt;/p&gt;
&lt;p&gt;Describing the sensitivity of the system, senior author Tarek Fahmy, Yale assistant professor of biomedical engineering, said:. &quot;Imagine I am the detector in a room where thousands of unrelated people are talking - and I whisper, &#039;Who knows me?&#039; I am so sensitive that I can hear even a few people saying, &#039;I do&#039; above the crowd noise. In the past, we could detect everyone talking - now we can hear the few above the many.&quot; &lt;/p&gt;
&lt;p&gt;According to the authors, this level of sensitivity and specificity is unprecedented in a system that uses no dyes or radioactivity. Beyond its sensitivity, they say, the beauty of this detection system is in its speed - producing results in seconds - and its compatibility with existing CMOS electronics.&lt;/p&gt;
&lt;p&gt;&quot;We simply took direction from Mother Nature and used the exquisitely sensitive and flexible detection of the immune system as the detector, and a basic physiological response of immune cells as the reporter,&quot; said postdoctoral fellow and lead author, Eric Stern. &quot;We coupled that with existing CMOS electronics to make it easily usable.&quot;&lt;/p&gt;
&lt;p&gt;The authors see a huge potential for the system in POC diagnostic centers in the US and in underdeveloped countries where healthcare facilities and clinics are lacking. He says it could be as simple as an iPod-like device with changeable cards to detect or diagnose disease. Importantly, Stern notes that the system produces no false positives - a necessity for POC testing.&lt;/p&gt;
&lt;p&gt;The authors suggest that in a clinic, assays could immediately determine which strain of flu a patient has, whether or not there is an HIV infection, or what strain of tuberculosis or coli bacteria is present. Currently, there are no electronic POC diagnostic devices available for disease detection. &quot;Instruments this sensitive could also play a role in detection of residual disease after antiviral treatments or chemotherapy,&quot; said Fahmy. &quot;They will help with one of the greatest challenges we face in treatment of disease - knowing if we got rid of all of it.&quot;&lt;/p&gt;

 <title>CNS-UCSB Helps Land $24 Million National Center to Study Environmental Impacts of Nanotechnology </title>
 <link>http://www.nanovip.com/node/53853</link>

  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;The Center for Nanotechnology in Society at the University of California at Santa Barbara (CNS-UCSB) helped to win the new University of California Center for the Environmental Implications of Nanotechnology&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Santa Barbara, Calif. – The Center for Nanotechnology in Society at the University of California at Santa Barbara (CNS-UCSB) helped to win the new University of California Center for the Environmental Implications of Nanotechnology (UC CEIN), a five-year, $24 million center co-funded by the National Science Foundation and the Environmental Protection Agency to study the environmental impacts of nanotechnology.  The new center, headquartered at UCLA but involving significant collaboration from UC Santa Barbara researchers, will include a research group on environmental risk perception led by Dr. Barbara Herr Harthorn, Director of the CNS-UCSB and Associate Professor of Feminist Studies, Anthropology &amp;amp; Sociology.  CNS-UCSB also will collaborate in the UC CEIN’s novel science journalist program, led by Professor William Freudenburg, a professor in UCSB’s Environmental Studies Program and a member of Harthorn’s team.  UC CEIN also includes other researchers in the Bren School of Environmental Science and Management, Environmental Studies, Chemistry, and Ecology, Evolution, and Marine Biology.&lt;/p&gt;
&lt;p&gt;“The new centers represent a promising step toward US development of much needed systematic knowledge about the environmental toxicology, ecology, and bioaccumulation of nanoparticles,” said Harthorn.  “Characterization of the hazards (and eventually, potential for exposures) associated with nanomaterial development and incorporation in other products is an essential next step in the responsible development of nanotechnologies.  CNS-UCSB researchers involved in the UC CEIN and our new collaborators look forward to assessing public perceptions of nanoparticle environmental hazards, and conducting systematic comparative analyses of risk and risk communication, as we work with UC CEIN toxicologists and ecologists to develop empirically based risk communication.”&lt;/p&gt;
&lt;p&gt;UC CEIN will be led by UCLA’s chief of nanomedicine, Dr. Andre Nel.  It was founded due to growing public, industry, and regulatory agencies’ interest in better understanding the environmental impacts of nanoparticles.  Combining interests in understanding nanoparticles’ effects in the environment, NSF and EPA sought out teams of university researchers to conduct such studies in a competition that was run over 2007 and 2008.  The presence of CNS-UCSB and its experience as an NSF Nanoscale Science and Engineering Center dedicated to research on the societal impacts of nanotechnologies contributed to the success of the UC CEIN in securing its $24 million award.&lt;/p&gt;
&lt;p&gt;Four of the seven Integrated Research Groups (IRGs) in the UC CEIN are based at UC Santa Barbara.  Harthorn’s IRG, which builds on her research team’s effort in the CNS-UCSB, also includes UCSB Environmental Studies professor William Freudenburg, University of British Columbia (UBC) environmental risk researchers Terre Satterfield and Milind Kandlikar, and Cardiff University’s social psychologist Nick Pidgeon.  In addition to Harthorn’s IRG, the other 3 at UCSB will be led by Arturo Keller, professor of environmental engineering in the Bren School of Environmental Science &amp;amp; Management and UC CEIN associate director; Bren professor of microbiology, Patricia Holden; and Bren associate professor of applied marine ecology, Hunter Lenihan.  Other researchers include Environmental Studies professor and chair, Josh Schimel; professor and vice chair in the  Department of Ecology, Roger Nisbet; EEMB assistant professor, Bradley Cardinale; and Galen Stucky, professor, Chemistry and Material Research Labs.  The UC CEIN collaboration will also include researchers at UC Davis, UC Riverside, Lawrence Livermore and Lawrence Berkeley National Laboratories, Columbia University, Germany&#039;s University of Bremen, and Nanyang Technological University in Singapore.&lt;br /&gt;
Funding for the center is part of the National Nanotechnology Initiative (NNI), a multi-agency federal program created to encourage development of nanotechnology in the U.S. economy.&lt;/p&gt;
&lt;p&gt;Science Background&lt;/p&gt;
&lt;p&gt;“Nanoscience involves research to discover new behaviors and properties of materials with dimensions at the nanoscale which ranges roughly from 1 to 100 nanometers(nm),” states the National Nanotechnology Initiative Web site.  One nanometer is one billionth of a meter.  “Nanotechnology is the way discoveries made at the nanoscale are put to work. Nanotechnology is more than throwing together a batch of nanoscale materials—it requires the ability to manipulate and control those materials in a useful way.”&lt;/p&gt;
&lt;p&gt;About CNS-UCSB&lt;/p&gt;
&lt;p&gt;The NSF Center for Nanotechnology in Society at UCSB serves as a national research and education center, a network hub among researchers and educators concerned with societal issues concerning nanotechnologies, and a resource base for studying these issues in the US and abroad. The Center addresses education for a new generation of social science and nanoscience professionals, and it conducts research on the historical context of the nano-enterprise, on innovation processes and global diffusion of nanotech, and on risk perception and the public sphere. CNS-UCSB researchers address a linked set of social and environmental issues regarding the domestic US and global creation, development, commercialization, production, consumption, and control of specific kinds of nanoscale technologies.  It is one of only two such centers in the country (the other is housed at Arizona State University).  The CNS research efforts are led by Dr. Harthorn and her UCSB Co-PIs, Professors Rich Appelbaum, Bruce Bimber, W. Patrick McCray, and Chris Newfield.&lt;/p&gt;

 <title>Green Nanotechnology Is Ready To Come Of Age</title>
 <link>http://www.nanovip.com/node/53852</link>
 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Alongside renewable energy, green tech is tipped to become employment sector number one in the next decades&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Alongside renewable energy, green tech is tipped to become employment sector number one in the next decades if you believe reports by major organizations covering green jobs. But my hunch is to keep a check of nano technology as well. Because green technology&#039;s tendency to thrive on clever solutions to reduce energy usage is all great but it boils down to a rather finite activity. Humans will look for the next challenge and switch their attention to those found in truly greening production of tangible materials. That’s in essence the domain of nanotechnology.&lt;/p&gt;
&lt;p&gt;Numbers of the National Science Foundation estimate that by 2015 nanotechnology will be worth $1 trillion in the world economy, employing over 2 million people .&lt;/p&gt;
&lt;p&gt;That compares to UN figures indicating that the global green economy of environmental products and services is estimated to double from US$1,370 billion (1.37 trillion) per year to US$2,740 billion (2.74 trillion) by 2020. The comparison makes little sense, I know, but hey, these are figures that are seldomly released so bear with me.&lt;/p&gt;
&lt;p&gt;For the time being there has been little reason to be all to obsessed with nanotechnology in a green context. That is because nano-engineered products are both intensely distrusted and overly hyped. We seem to be aware of the technology&#039;s potential in a positive sense yet there’s also a tremendous amount of skepticism because toxic substances are often created in the process that ordinary technology can’t handle.&lt;/p&gt;
&lt;p&gt;But then again, those few nano-products that actually are green at the core are incredibly laudable. One example is the production of environmentally friendly gold particles, a recent development that the manufacturing marketplace is already wildly enthusiastic about. GreenNano, the new nanotech company that started commercializing eco-friendly gold nano-particles is receiving lots of press attention. The man who heads it all up, Kattesh Katti, is the renowned professor of radiology and physics attached to the University of Missouri&#039;s School of Medicine and College of Arts and Science.&lt;/p&gt;
&lt;p&gt;Gold nano-particles are used in industrial applications ranging from cancer treatment to automobile sensors to cell phones and hydrogen gas production. The (patent pending) method Katti has invented eliminates synthetic chemicals involved in the production of gold nano-particles. That means that the production process is entirely environmentally friendly.&lt;/p&gt;
&lt;p&gt;GreenNano submerses gold salts in water and then adds soybeans. A complex but wholly natural process leads to the creation of gold nano-particles. Sounds almost too good to be true, but more curious things have known to have occurred in the nano-business (including the growth of cell phones on plants).&lt;/p&gt;
&lt;p&gt;GreenNano Company is in the midst of developing, commercializing and organizing the supply of gold nano particles for medical and technological applications. In my view the most exciting thing is that the creation, marketing and distribution of the new product is not where the story ends. According to Professor Katti, because the production procedure has changed so profoundly, other researchers are developing new uses for the technology.&lt;/p&gt;
&lt;p&gt;In other words, we’re evolving!&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;

 <title>What Is A Career In Biotechnology Like? </title>

 <description>&lt;div class=&quot;field field-type-text field-field-short-description&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Short description&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Biotechnology is the integration of engineering and technology to the life sciences.&lt;/p&gt;
&lt;/div&gt;
      &lt;/div&gt;
&lt;/div&gt;

&lt;div class=&quot;field field-type-text field-field-article-body&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Article body&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
          &lt;div class=&quot;field-item&quot;&gt;&lt;p&gt;Biotechnologists frequently use microorganisms or biological substances to perform specific processes or for manufacturing. Examples include the production of drugs, hormones, foods and converting waste products.&lt;/p&gt;
&lt;p&gt;There are many sub-branches involved in the biotech industry. A few of the more common branches include; molecular biology, genetic engineering, and cell biology.&lt;/p&gt;
&lt;p&gt;A new and exciting sub-branch requiring biotechnologists is the field of nanotechnology. Nanotechnology gives us the capability to engineer the tiniest of objects, things at the molecular level. Nano means a billionth of a specific unit in Greek. Nanotechnology includes the study and manipulation of materials between 1 and 100 nanometers.&lt;/p&gt;
&lt;p&gt;To give you an idea, DNA is approximately 2.5 nanometers. Red blood cells are 2.5 micrometers (1,000 times larger). And a sheet of paper is about 100,000 nanometers thick!&lt;/p&gt;
&lt;p&gt;As you can imagine, it is very difficult to scale and mass produce objects within the realm of nanotechnology. Their minute size makes them nearly impossible to manipulate. But scientists and engineers have teamed up to make the seemingly impossible a reality.&lt;/p&gt;
&lt;p&gt;Which means those with the proper training will be highly sought after in the future. The National Science Foundation estimates that the U.S. alone will need up to 1 million nanotechnology researchers. It is estimated that the need for nanotechnology workers will reach 2 million by 2015.&lt;/p&gt;
&lt;p&gt;Therefore, if you?re considering getting into the field of biotech, you may want to gear your background in nanotechnology if your school offers it or seek employment in this exciting new career field after graduating.&lt;/p&gt;
&lt;p&gt;No matter what sub-branch you wind up specializing in, biotechnologists often collaborate with others in the laboratory and bounce ideas off one another. This can create a pleasant work environment; one that involves sharing with others and working together to achieve a great goal.&lt;/p&gt;
