Nanobots ,simply are the robots at the nanoscale level which is being researched currently with the hope that it might benefit greatly in the medical field and other several fields as well. Several efforts have been made to develop it but we still have a long way to go before we can see it being used in human body. So, this is still a hypothetical concept at present.Nanotechnology is a revolutionary idea in itself. In the future , nanobots might become a part of our everyday life greatly affecting the products and services we use.
