Nanotechnology has potential application in diagnosis, imaging and treatment of cancer. The different nanomedicine likes nanoshells, nanowires, superparamagnetic nanoparticles and a surface modified nanoparticle has been used in cancer treatment for targeted action. The nanowires are placed across microfludic channel which interact with molecular markers of cancer cells. Nanoscale cantilevers work depend on the semiconductor lithographic Techaniques. The cantilevers are coated by antibodies which interact with special molecules secreted by cancer cells. In now a day’s the potential toxicity of nanoparticles due to their smaller size related to human and enviourment are also of great concerned.
