nanotechnology    
nanotechnology
n 1: the branch of engineering that deals with things smaller
than 100 nanometers (especially with the manipulation of
individual molecules)

nanotechnology \nan"o*tech*nol`o*gy\
(n[a^]n"[-o]*t[e^]k*n[o^]l`[-o]*j[=e]), n.
The manipulation or construction of objects with sizes in the
nanometer range or smaller.

Note: Objects of the size of molecules may be moved and
placed in specific locations using laser tweezers or an
atomic force microscope. See [a

[PJC]

/nan'-oh-tek-no"l*-jee/ Any fabrication technology in which
objects are designed and built by the specification and
placement of individual atoms or molecules or where at least
one dimension is on a scale of {nanometers}.

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.

{Richard P. Feynman's initial public discussion in 1959-12-29
(http://www.zyvex.com/nanotech/feynman.html)} lead to the
{Feynman Prize for Nanotechnology
(http://www.foresight.org/FI/fi_spons.html)}. Erik Drexler
coined the term about 30 years later in his book "Engines of
Creation", where he predicted that nanotechnology could give
rise to replicating assemblers, permitting an exponential
growth of productivity and personal wealth.

nanotechnology: /nan'·oh·tek·no`l@·jee/, n. 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.org/EOC/index.html).
