'Nanotechnology' is a hybrid science combining engineering, information technology, chemistry and biology. The goal of Nanotechnology is to manipulate atoms individually at nanoscale dimensions. It is not just a miniaturization process but also a 'bottom-up' manufacturing approach of building atoms by atoms using Molecular assemblers. The need of the hour is to build a molecular assembler. Nano-scientists all over the world are advancing towards that direction. Implicit applications of this emerging technology are infinite, ranging from Supercomputing, Raising the dead, Stain-resistant fabrics, Painless surgeries, Ensuring a clean environment etc.
