Welcome to the fascinating and astonishing/wonderful world of Nanotechnology, where the amazing inventions and discoveries are made by research and development centers at the level of far below than that can be observed by the naked eyes.

Nanotechnology manipulation of atoms, molecules and materials to form structure on the scale of nanometers (one billionth of a meter) it is around 10,000 to 50,000 times smaller than the diameter of hair. These nanostructures due to QUANTUM MACHANICS. In 1959 RECHARD FEYMAN First pointed out some potential quantum benefits of miniaturization. A major advancement was the invention of molecular beam epitaxy by Alfared Cho and John Arthur at Bell laboratories. The term Nanotechnology was first coined in 1974 by Prof.Norio Taniguchi at the Tokyo science University. He used this term to measure the precision manufactured of material in the scale of nanometer.

The main purpose of nanotechnology is to manipulate individual atoms and molecules in the manufacture of computer chips and other devices. Which are many times smaller than the existing devices.

Nanotechnology is broadly classified into three categories:

• Nanomaterial’s
• Nanoelectronics’
• Nanobiotechnology

Nanotechnology: nanotechnology refer to a field of applied science. The main concept of nanotechnology is to control individual atoms and molecules.

Nanotechnology is a multidisciplinary field. Nanotechnology has the potecntial to create many new materials and devices with the wide range of applications such as medicines electronic devices and energy production.

To the put the scale in another contest, the comparative size of a nanometer to a meter is same as that of marble to the size of the earth.

Application: Nanotechnology is used in wide range of application
