2. Nanotechnology is the art and science of manipulating matter
at an atomic scale Making new things on an incredibly small scale
is called nanotechnology. It's one of the most exciting and
fast-moving areas of science and technology today. With 15,342
atoms, this parallel-shaft speed reducer gear is one of the largest
Nano-mechanical devices ever modeled in atomic detail.
3. Technically, Nano means one-billionth. So nanometer is one
billionth of a meter. 1 nanometer = 10-9 meters The Nano scale is
1000 times smaller than the microscopic scale and a billion (1000
million) times smaller than the world of meters that we live in.
Its difficult to imagine just how small that is....
4. A sheet of paper is about 100,000 nanometers thick. One
nanometer is about as long as your fingernail grows in one second.
There are 25,400,000 nanometers in one inch Here are some examples
;
5. Nanotechnology has been around as a recognized branch of
science for only about fifty years. When we want more in a smaller
package, component size must be reduced, and this increasingly
involves working with components at the Nano-scale. Evolution of
nanoechnology has been the most important to silicone chip
technology...
6. The first point contact transistor built in 1947. Intel's 32
nm Nehalem chip architecture incorporates around 1.9 billion
transistors in a single chip.
7. Can create unique materials and products which are; Stronger
Lighter Cheaper Durable Computers can become billion times faster
and million times smaller. Can be used to cure illnesses. (eg:
Cancer, AIDS) Effective energy-producing, energy-absorbing, and
energy storage products in smaller and more efficient devices is
possible.
8. Nanotechnologies to be more specific: nanomaterial's are
already used in numerous products and industrial applications.
9. USE OF NANOTECHNOLOGY IN HEALTH CARE The use of
nanotechnology in medicine offers some exciting possibilities. Some
techniques are only imagined, while others are at various stages of
testing, or actually being used today. The use of nanotechnology in
the field of medicine could revolutionize the way we detect and
treat damage to the human body and diseases in the future.
10. One application of nanotechnology in medicine currently
being developed is deliver drugs, heat, light or other substances
to specific types of cells. Particles are engineered so that they
are attracted to diseased cells, which allows direct treatment of
those cells. Treatment for Cancer Cells
11. USE OF NANOTECHNOLOGY IN CONSUMER PRODUCTS Nano has already
found its way into lots of products you use every day, from
clothing to tennis racquets. If you strolled around your home youd
probably find dozens of products manufactured using some kind of
nanotechnology.
12. A hydrophobic coating glove that repels water and refined
oils using nanotechnology
13. Health Issues - The effects of nanomaterial's on human
biology Nano particles can serious illness or damage human body.
Untraceble destructive weapons of mass destruction. Environmental
Issues - The effects of nanomaterial's on the environment
Nanopollution is created by manufacturing of nano-particles.
Contributes to global warming.
14. Social & Political Issues - The effects that the
availability of Nano-technological devices will have on politics
and human interaction Create social strife through increasing
wealth gap. Advisability of increasing scope of the technology
creates political dilemma Grey Goo Its a hypotetical situation
where self replicating Nanobots go out of control, and consume all
the matter on Earth.
15. Nanotechnology will be the one science of the future that
no other science can live without.
16. Use Of Nanotechnology (BuckyPaper) In The Future Buckypaper
is a thin sheet made from an aggregate of carbon nanotubes The
nanotubes are approximately 50,000 times thinner than a human
hair.
17. The future of nanotechnology could very well include the
use of NanoRobotics. There would be an entire nano surgical field
to help cure everything natural aging to diabetes to bone
spurs.
