Nanotechnology is the manipulation of matter on an atomic and molecular scale, working with materials, devices, and other structures with at least one dimension sized from 1 to 100 nanometres. Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication and more.
