Nanotechnology in Medicine Application: 1)Drug DeliveryFor example, nanoparticles thatdeliver chemotherapy drugs directly to cancer cellsare under development.

2)Therapy Techniques

Researchers have developed "nanosponges" that absorb toxins and remove them from the bloodstream. Thenanospongesare polymer nanoparticles coated with a red blood cell membrane. The red blood cell membrane allows the nanosponges to travel freely in the bloodstream and attract the toxins.

3) Diagnostic Techniques

Researchers at Worcester Polytechnic Institute are usingantibodies attached to carbon nanotubesin chips to detect cancer cells in the blood stream. The researchers believe this method could be used in simple lab tests that could provide early detection of cancer cells in the

4)Anti-Microbial Techniques

Researchers at the University of Houston are developing a technique to kill bacteria usinggold nanoparticles and infrared light. This method may lead to improved cleaning of instruments in hospital settings.

5)Cell Repair

Nanorobots could actually be programmed to repair specific diseased cells, functioning in a similar way to antibodies in our natural healing processes.
