Nano technology simply refers to devices and materials fabricated on this type of scale.
To manipulate each individual atom of an object is the basic idea of Nanotechnology. Such devices and materials can be built in two ways using Macroscopic Fabrication techniques.1)Bottom up approach2) Top Down approach Nano technology is not confined to limited number of fields. Every area of industry, Health and environment can be improved using this.With the Discovery of techniques to organize, characterize and manipulate individual elements of matter as well as the increasing insights into self organization principles of these elements the world wide industrial conquest of nanoscale dimensions began. The prospect of injecting patients with machines to make repairs, of rating super-strong and like materials for space exploration, of restoring environmental systems on a molecular level are all parts of the promise of Nanotechnolgy.
