Nano science and technology is the modern world concept which is based on the science of tiny particle within the size range at least one dimension sized from 1 to 100 nanometers. Nanotechnology deals with fabrication and manipulation of the matter on an atomic, molecular and supramolecular level. Nanotechnology is going to carve a niche in broad and diversified field of science including micro fabrication, semiconductor, surface science, medicine and organic chemistry etc. The term nanomaterial includes all nanosized materials, including materials that can be engineered or found in nature. Nanotechnology can be described as the technology of composite functional systems at the nano scale of the materials. They are important because they exhibit unique properties which are significantly different from their conventional bulk counterpart. Because of their unique features in terms of size and properties nano-scientists and engineers have explored the technology to invent new miracle in diversified field of sciences.
