Nano-electronic devices have positive and negative advantages, as some countries have launched studies on this technology, and other countries have established research and studies centers and universities dedicated to nanotechnology, and commissioned a group of distinguished experts to study this technology. Thousands of years ago, humans intended to use nanotechnology. For example I use in the steel and rubber industry. They are all based on the properties of atomic groups of nanometers in random formations. It is distinguished from chemistry in that it does not depend on the individual properties of molecules. The first to some distinct concepts in nanotechnology (preceding but using this name) in 1867 writer James Maxwell when she proposed the idea of ​​an experiment Small entity Maxwell defines the devil from the processing of individual particles. In the 1920s, Irving Langmuir and Catherine Blodgett introduced the concept of a monolayer system, i.e. a single atomic layer or layer of matter with a thickness of atomic scales. Langmuir won the Nobel Prize in Chemistry for his work.
