Nano science Nanoscience is the bundling of sciences that together target human control over the arrangement of atoms and molecules on the nanoscale, this is the scale of individual atoms and molecules Nanoscience is the science of the extremely small – objects smaller than 100 nanometers

BASIC OF NANO

(for comparison, a human hair is 80 000 nm wide) NANOTECHNOLOGY Nanotechnology is based on the ideas of Nano science. Dealing with things smaller than100 nano meters. Nanotechnologies are poised to provide fantastically light and strong materials (for comparison, a human hair is 80 000 nm wide)

Some facts we know A team of German and Swiss scientists has calculated that nano-forces allow spiders to carry more than 170 times their own body weight. A Japanese company has developed 10 nm-diameter particles that coat pollen and stop it releasing hay fever- causing allergens. In Florida, USA, have devised a nano particle based bioassay that can detect a single bacterium within 20 minutes.

Uses of Nanotechnology Medical field The wound dressings that exploit the antimicrobial properties of nanocrystalline silver. Nano materials could make good security. Nanoparticles such as nanocrystalline zirconium oxide (zirconium) and nanocrystalline silicon carbide are strong, lightweight, resistant to wear and corrosion and (unlike many other nanoparticles) inert 1

Aluminosilicate nanoparticles can more quickly reduce bleeding trauma patients by absorbing water, causing blood in a wound to clot quickly. Z-Medica is producing a medical gauze that uses aluminosilicate nanoparticles.

REPLACEMENT OF MICROWAVES BY NANOSCALE SPIN WAVES Communication REPLACEMENT OF MICROWAVES BY NANOSCALE SPIN WAVES The aim of the research project, which started two years ago, has been to demonstrate the propagation of spin waves from magnetic nanocontacts. Last autumn, the group was able to demonstrate the existence of spin waves with the aid of electrical measurements, and the results were published in the scientific journal Physical Review Letters. The new results have been published in Nature Nanotechnology, the most prestigious journal in nanoscience.

Future Invention Developing CMOS technology for IC's using sub-22nm geometry and Nanoforms Nanotube based transparent conductive film for use in applications such as LCD displays and e-paper

Production of Cartilage Nano fibers Nanofibers can stimulate the PRODUCTION OF CARTILAGE in damaged joints. Nanoparticles may be used, when inhaled, to STIMULATE AN IMMUNE SYSTEM RESPONSE TO FIGHT RESPIRATORY VIRUSES
