Nanotechnology is the next big thing

While the debate over genetically modified organisms has sometimes become absurd, there are important lessons to be learnt from the whole process. Barely a year ago, terms such as biosafety, GMO or transgenics, used to describe these technologies, were a preserve of a small elite group of scientists and lobbyists. However, today, these are to be heard in public meetings ... Read More »

Electric motor made from a single molecule

Researchers have created the smallest electric motor ever devised. The motor, made from a single molecule just a billionth of a metre across, is reported in Nature Nanotechnology. The minuscule motor could have applications in both nanotechnology and in medicine, where tiny amounts of work can be put to efficient use. Tiny rotors based on single molecules have been shown ...

Nanorobots: Novel Technology for Cancer Therapy

Human knowledge, with all its growth and development, is still in its initial stages of finding efficient ways to treat cancer. The elevated number of cancer patients puts cancer treatment amongst the top priority of scientific research facilities. The advent of nanotechnology opens new windows that promise effective ways in locating the chemical sources, tracking them, controlling the cancerous cells, ... Read More »

The Risk of Nanotechnology

Developing countries forging ahead with nanotechnology need regulation and research into local risk patterns, say Alok Dhawan andVyom Sharma. Nanotechnology, the science of manipulating tiny particles less than 100 nanometers in diameter, has found many applications in consumer products, biomedical devices, drug delivery agents and the industrial sector. In the consumer sector alone, more than 30 countries are manufacturing some ... Read More »
