- 3. What is Nano Technology Nanotechnology is engineering and manufacturing at the molecular scale, thereby taking more advantage of the unique properties that exist at that scale. Can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. A Nanometre is a unit of length in the metric system, equal to one billionth of a metre(10-9).
- 4. What is Nanoscale ? Fullerene C60 12,756 KM 22 CM 0.7MM 1.27 x 10 ^7m 0.22 m 0.7 x 10^-9 m 10 Millions times smaller 10 Billion times smaller
- 5. History The first ever concept was presented in 1959 by the famous professor of physics Dr. Richard P.Feynman. Invention of the scanning tunneling microscope in 1981 and the discovery of fullerene(C60) in 1985 lead to the emergence of nanotechnology. The term “Nano-technology" had been coined by Norio Taniguchi in 1974
- 6. Assembling Nano materials atom-by- atom or molecule-by-molecule (self assembling) Approaches in Nanotechnology Top-Down Bottom-Up Creating nano-scale materials by physically or chemically breaking down lager materials
- 7. • There are several important modern developments. • The atomic force microscope (AFM). • The Scanning Tunneling Microscope (STM) are scanning probes that launched nanotechnology. 2 .Various techniques of nanolithography such as: • optical lithography. • X-ray lithography, • Dip pen nanolithography • Electron beam lithography(inkjet printer) • were also developed. Lithography in MEMS context is typically the transfer of a pattern into a photosensitivematerialbyselectiveexposuretoaradiationsourcesuchaslight.

Nanotechnology in Drugs(Cancer)
- 10. • The properties of familiar materials are being changed by manufacturers who are adding nano-sized components to conventional materials to improve performance. • For example, some clothing manufacturers are making water and stain repellent clothing using nano-sized whiskers in the fabric that cause water to bead up on the surface. • In manufacturing bullet proof jackets. • Making spill & dirt resistant, antimicrobial, antibacterial fabrics. Nanotechnology in Fabrics
- 11. • Morph, a nanotechnology concept device developed by Nokia Research Center (NRC) and the University of Cambridge (UK). • The Morph will be super hydrophobic making it extremely dirt repellent. • It will be able to charge itself from available light sources using photovoltaic nanowire grass covering it's surface. • Nanoscale electronics also allow stretching. Nokia envisage that a nanoscale mesh of fibers will allow our mobile devices to be bent, stretched and folded into any number of conceivable shapes. Nanotechnology in Mobile
- 12. • Electrodes made from nanowires enable flat panel displays to be flexible as well as thinner than current flat panel displays. • Nanolithography is used for fabrication of chips. • The transistors are made of nanowires, that are assembled on glass or thin films of flexible plastic. • E-paper, displays on sunglasses and map on car windshields. Nanotechnology in Electronics
- 13. • The silicon transistors in your computer may be replaced by transistors based on carbon nanotubes. • A carbon nanotube is a molecule in form of a hollow cylinder with a diameter of around a nanometer which consists of pure carbon. • Nanorods is a upcoming technology in the displays techniques due to less consumption of electricity and less heat emission. • Size of the microprocessors are reduced to greater extend. • Researchers at North Carolina State University says that growing arrays of magnetic nanoparticles, called nanodots. Nanotechnology in computers
- 14. • Nanotechnology may make it possible to manufacture lighter, stronger, and programmable materials that - require less energy to produce than conventional material - and that promise greater fuel efficiency in land transportation, ships, aircraft, and space vehicles. • The future of nanotechnology could very well include the use of nanorobotics. • These nanorobots have the potential to take on human tasks as well as tasks that humans could never complete. The rebuilding of the depleted ozone layer could potentially be able to be performed. Possibilities for the future
- 15. • Nano-particles can get into the body through the skin, lungs and digestive system, thus creating free radicals that can cause cell damage. • Once nano-particles are in the bloodstream, they will be able to cross the blood-brain barrier. • The most dangerous Nano-application use for military purposes is the Nano-bomb that contain engineered self multiplying deadly viruses that can continue to wipe out a community, country or even a civilization. • Nanobots because of their replicating behavior can be big threat for GRAY GOO. Pitfalls of nanotechnology
- 16. • By using Once Nano-Technology we can make unique material which are - Stronger, Lighter, cheaper, Durable, Precise. • Computer can become a billion times faster and a million time smaller • Manufacturing at almost low cost Conclusions
