Nanodevices are the product of nanotechnology that is small sized device capable of performing multi functions at the same time. Among many such examples of nanodevices, one is nano scale cantilever that is primarily used to detect cancer cells. Drug delivery using such devices have tremendous scope and is more efficient that the traditional methods of drug delivery. These nanomaterials field includes subfields that develop or study materials having distinctive properties arising from their nanoscale dimensions.Nanodevices are nanoparticles that are created for the purpose of interacting with cells and tissues and carrying out very specific tasks. The most famous nanodevices are the imaging tools. Oral pills can be taken that contain miniature cameras. These cameras can reach deep parts of the body and provide high-resolution pictures of cells as small as 1 μm in width. (A red blood cell is 7 μm wide.)
