Albert Einstein first proved that each molecule measures about a nanometer (a billion of a meter) in diameter. And in 1959, it was Richard P. Feynman who predicted a technological world composed of self-replicating molecules whose purpose would be the production of nano-sized objects.
Introduction
The development and use of devices that have a size of only a few nanometres. Research has been carried out into very small components, which depend on electronic effects and may involve movement of a countable number of electrons in their action. Such devices would act faster than larger components. Considerable interest has been shown in the production of structures on a molecular level by suitable sequences of chemical reactions. It is also possible to manipulate individual atoms on surfaces using a variant of the atomic force microscope.
Nanotechnology is the creation of functional materials, devices and systems through control of matter on the nanometer length scale (1-100 nanometers), and exploitation of novel phenomena and properties (physical, chemical, biological) at that length scale. For comparison, 10 nanometers is 1000 times smaller than the diameter of a human hair. A scientific and technical revolution has just begun based upon the ability to systematically organize and manipulate matter at nanoscale. Payoff is anticipated within the next 10-15 years.
A push is well underway to invent devices that manufacture at almost no cost, by treating atoms discretely, like computers treat bits of information. This would allow automatic construction of consumer goods without traditional labor, like a Xerox machine produces unlimited copies without a human retyping the original information.
Working at the resolution limit of matter, it will enable the ultimate in miniaturization and performance. By starting with cheap, abundant components--molecules--and processing them with small, high-frequency, high-productivity machines, it will make products inexpensive.
