General
-
Nanotechnology refers to a field of applied science and technology whose
theme is the control of matter on the atomic and molecular scale,
generally 100 nanometers or smaller, and the fabrication of devices or
materials that lie within that size range.
-
Nanotechnology is any technology which exploits phenomena and structures
that can only occur at the nanometer scale, which is the scale of
several atoms and small molecules.
-
Nanotechnologies are based on a range of new materials, including carbon
C60, carbon nano tubes, nano particles, nano wires, and polymers based
on nano-size subunits.
Technology
- The nano
tools of nano structured materials are used to make items like nano
tubes, nano electronics, nanocatalysts, nanophotonic devices,
nanosensors and other nano devices.
- Two main
approaches are used in nanotechnology. In the "bottom-up" approach,
materials and devices are built from molecular components which assemble
themselves chemically by principles of molecular recognition.
- In
the "top-down" approach, nano-objects are constructed from larger
entities without atomic-level control.
- Interface
and Colloid Science for characterizing nano materials, These are widely
used for first generation passive nano materials
Market
-
Nanotechnology products in semiconductor, energy, healthcare, materials
science, and instrumentation have created existing nanotechnology
markets of $499 million growth expected to achieve markets of $4.5
billion
-
The total global demand for
nano scale materials, devices and tools will cross $28 billion.
-
The U.S. Nanotechnology market
is predicted to reach $3.3 billion it will cross $19.8 billion by
showing a strong growth.
Application
-
Passive nano
materials which includes titanium dioxide in sunscreen, cosmetics and some
food products.
-
Carbon allotropes
used to produce gecko tape, silver in food packaging, clothing,
disinfectants and household appliances.
-
zinc oxide in
sunscreens and cosmetics, surface coatings, paints and outdoor furniture
varnishes and cerium oxide as a fuel catalyst.
