Nanotechnology -What is it?
Nanotechnology
is a field of applied science and technology .This
technology is concerned with the control of matter on a
scale smaller than 1 micrometer, generally between 1-100
nanometers, as well as the production of devices on this
same length scale. The term "nanotechnology" was defined
by Tokyo Science University Professor Norio Taniguchi in a
1974 paper as follows:
Definition of Nano Technology:
"'Nano-technology' mainly consists of the processing
of, separation, consolidation, and deformation of
materials by one atom or one molecule." A imporatant concept of nanotechnology is the largely
increased ratio of surface area to volume present in many
nanoscale materials.
Applications include titanium dioxide and zinc oxide
nanoparticles in sunscreen, cosmetics, silver
nanoparticles in food packaging, clothing, disinfectants
and household appliances, surface coatings and paints.
