Random House Webster's College Dictionary
nan•o•tech•nol•o•gyˈnæn ə tɛkˌnɒl ə dʒi, ˈneɪ nə-(n.)
a technology executed on the scale of less than 100 nanometers, the goal of which is to control individual atoms and molecules, esp. to create computer chips and other microscopic devices.
Category: Weights and Measures
Origin of nanotechnology:
the branch of engineering that deals with things smaller than 100 nanometers (especially with the manipulation of individual molecules)
the science and technology of creating nanoparticles and of manufacturing machines which have sizes within the range of nanometres
Nanotechnology is the manipulation of matter on an atomic and molecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications, governments have invested billions of dollars in nanotechnology research. Through its National Nanotechnology Initiative, the USA has invested 3.7 billion dollars. The European Union has invested 1.2 billion and Japan 750 million dollars.
The New Hacker's Dictionary
A hypothetical fabrication technology in which objects are designed and built with the individual specification and placement of each separate atom. The first unequivocal nanofabrication experiments took place in 1990, for example with the deposition of individual xenon atoms on a nickel substrate to spell the logo of a certain very large computer company. Nanotechnology has been a hot topic in the hacker subculture ever since the term was coined by K. Eric Drexler in his book Engines of Creation (Anchor/Doubleday, ISBN 0-385-19973-2), where he predicted that nanotechnology could give rise to replicating assemblers, permitting an exponential growth of productivity and personal wealth (there's an authorized transcription at http://www.foresight.o/definition/index). See also blue goo, gray goo, nanobot.
U.S. National Library of Medicine
The development and use of techniques to study physical phenomena and construct structures in the nanoscale size range or smaller.
