Nanotechnology is the scientific study of substance in their molecular form. This particular branch of science is being implemented in major streams of science such as physics, biology, chemistry, etc. In the recent years, nanotechnologies are revolutionizing future devices and applications that help in better living and have been proved very useful in industrial sectors. Although most of its work is in the development phase many of its application are being used commercially with positive outputs. Here we will concentrate on the topic how useful is the applications of nanotechnology in medicine and nanosurgery.
