what is the nanotech?
Nanotechnology (" nanotech ") is manipulation of matter on an atomic , molecular , and supramolecular scale. The earliest, widespread description of nanotechnology [1] [2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology . A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative , which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers . This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the give...
