Nano particles are sometimes characterised as materials with one or more dimensions of smaller than 100 nm and, as a result, have unique properties distinct from their bulk equivalents or atomic / molecular constituents. Because of their small size and thus high surface to volume ratio, nano particle materials have recently been the subject of active research. The subject of nano science has grown at an exponential rate year after year due to novel synthetic methods and the availability of new equipment. characterization. The 2016 Nobel Prizes in Physics and Chemistry highlight the development and importance of path breaking discoveries in nano materials for the future and benefit of the mankind
