What is it Nanotechnology?

Sometimes shortened to "Nanotech", refers to a field whose theme is the control of matter on an atomic and molecular scale.
Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size.
Thus it is the science of building machines at subatomic level
Nanotechnology deals with materials and machines on an incredibly tiny scale - less than one billionth of a meter; smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair

Origin of the term

In 1986, K. Eric Drexler wrote "Engines of Creation" and introduced the term nanotechnology
Officially the term "nanotechnology" was first defined by Norio Taniguchi of the Tokyo Science University in a 1974 paper as follows:
'Nano Technology' mainly consists of the processing of, separation, consolidation, and deformation of materials by one atom or one molecule." Since that time the definition of nanotechnology has generally been extended to include features as large as 100 nm. Additionally, the idea that nanotechnology embraces structures exhibiting quantum mechanical aspects, such as quantum dots, has further evolved its definition.

However its conceptual origin can be traced back to 1959, when physicist and Nobel prize winner Richard...
