What is nano technology?
Although nanotechnology is a relatively recent development in scientific research, the development of its central concepts happened over a longer period of time.
One Definition
Nanotechnology, the creation and use of materials or devices at extremely small scales.
History
Humans have unwittingly employed nanotechnology for thousands of years, for example in making steel and in vulcanizing rubber. Both of these processes rely on the properties of stochastically-formed atomic ensembles mere nanometers in size, and are distinguished from chemistry in that they don't rely on the properties of individual molecules. But the development of the body of concepts now subsumed under the term nanotechnology has been slower
