Nanotechnology is the branch of science and technology that deals with the things on nanometric scale. It is well established that the properties of materials at this scale are entirely different from those at the bulk level, such as fullerenes are known to be superconducting and carbon nano tubes have optical, electrical and mechanical behaviors entirely different. The physics of quantum dots has added a new dimension to the existing knowledge. Infact the subject is so exciting and versatile that it has made inroads in all branches of science. One talks of nanoelectronics, nanophotonics, nanobiotechnology, nanomedicine, nanorobotics etc. Nanomaterials play important role in the modern development of science due to its small size and large surface area.
