Battling Cancer with Nanotechnologies

In the March issue of Mechanical Engineering in an article entitled “Infernal Mechanism,” Mauro Ferrari, PhD writes of a nanotechnology based agents that can exploit cancer and its mechanical properties.  This method for fighting cancer will allow doctors to treat cancer in its various forms locally.

Ferrari works at the University of Texas Health Science Center; he is the chairman and professor of the Department of Nanomedicine and Biomedical Engineering.  Ferrari explains that engineered nanoparticles can be used as therapeutic agents which can be used to deliver cancer defensive drugs to areas in the human body that are affected by the disease; this will allow doctors to keep healthy cells healthy while reducing and destroying cancerous lesions.  What’s more, nanotechnologies can be utilized to minimize the serious side effects that patients experience from cancer drug treatments.

Ferrari explains that one must understand how cancer is treated to really understand the true innovation of this novel drug delivery system.  According to Ferrari the way cancer malignancies spread through the body via metastasis and angionenesis are phenomena that pertain to the movement and transport of cells and blood.  Nanotech based therapy currently being tested for future cancer treatments are taking advantage of such movements in order to find innovative methods for destroying cancer cells.  A new field is now being developed called “transport oncophysics.”

Nanoparticles containing cancer fighting drugs can conquer biological barriers; they can leak through small blood vessels and enter a tumor to deliver concentrated drugs to cancer cells.  This means that in the future, cancer drugs can be delivered in more precise, far smaller doses and such drugs are far less likely to have any kind of effect on the remainder of the human body.  Ferrari, working along with a team of nanotech researchers at the University of Texas, has also created Multi State vectors, nanoparticles that can be used to target single cancer cells.  Ferrari explains that society is on the verge of witnessing a new era when it comes to the way cancer is treated.

Mauro Ferrari spoke on February 8^th at the First Global Congress on Nanoengineering for Medicine and Biology.  The conference was sponsored by ASME and  in Houston Texas.  According to Ferrari, the amount of specificity that can actually be achieved through the use of the novel nanotech-based therapy agents will clearly improve therapeutic efficacy and will help to ultimately minimize the serious side effects associated with cancer treatments.
