Nano Technology

Nanotechnology is the creation of useful/functionalmaterials, devices and systems (of any useful size) through control/manipulation of matter on the nanometer length scale at dimensions of approximately 1 – 100 nanometerand exploitation of novel phenomena and properties which arise because of the nanometer length scale that include change inphysical (e.g. melting point), chemical (e.g. reactivity), electrical (e.g. conductivity), mechanical (e.g. strength), optical properties (e.g. light emission) andsurface reactivity (Adsorption) etc.
