Drug molecules are dumped into the body where they are transported by the circulatory system. They may come into contact with un-targeted parts of the body and lead to unwanted side effects. Nanomedical robots, however, will have no difficulty identifying cancer cells and will ultimately be able to track them down and destroy them wherever they may be growing. This is why the medical profession is looking towards the use of biomedical, nanotechnological engineering to refine the treatment of diseases. 2 Nanorobots will typically be .5 to 3 microns large with 1-100 nm parts. Three microns is the upper limit of any nanorobot because nanorobots of larger size will block capillary flow(Freitas 26). The nanorobot's structure will have two spaces that will consist of an interior and exterior. The exterior of the nanorobot will ...
