It is expected that nanotechnology will provide a significant breakthrough in computer technology, in medicine and in the military. For example, medical science has developed ways to deliver drugs directly to cancerous tissues in a tiny "nanobomb". In the future nanodevices can "patrol" the arteries, preventing infections and providing a diagnosis.
American scientists have successfully used covered with gold "nanopoly" for the search and destruction of inoperable cancerous tumors. Scientists have NanoPole attached to antibodies, which are able to contact with cancer cells. If to expose "nanopoly" the effect of radiation, similar in frequency to the infrared, their temperature will increase, which contributes to the destruction of carcinogenic tissues.
