Nanotechnology encompasses science and technology related to the study and application of materials, machinery and other nanoscale components. Nano is equal to one billionth of a meter. Is a research field that seeks to create new materials and applications depend on tiny machines or special qualities.
The nanomedicine is a branch of nanotechnology that could allow healing and nfremedades from inside the body and cellular or molecular level.
An example of nanomedicine are biosensors that are new ways to deliver drugs more efficiently and directly, and to develop new materials for grafting. Biosensors have been used to detect the presence of anthrax. Another application of biosensors is in diabetic patients, which would be favored to take insulin encapsulated in artificial cells to be let out when you increase blood glucose.
