Abstract:
The
aim of technology is to make products in a large scale for cheaper prices and
increased quality. The current technologies have attained a part of it, but the
manufacturing technology is at macro level. The future lies in manufacturing
product right from the molecular level. Research in this direction started way
back in eighties. At that time manufacturing at molecular and atomic level was
laughed about. But due to advent of nanotechnology we have realized it to a
certain level.
Nanotechnology
is the science of the extremely tiny. It involves the study and use of
materials on an unimaginably small scale. Nano refers to a nanometre (nm). One
nanometre is a millionth of a millimetre or about one eighty thousandth the
width of a human hair. There are one billion nm's to a meter. Each nm
is only three to five atoms wide.
