WHAT IS NANOTECHNOLOGY?
Nanotechnology is the study of manipulating matter on a atomic or molecular scale.

APPLICATIONS OF NANOTECHNOLOGY

 * __Medicine__ is used to deliver drugs, heat, light and other substances to certain types of cells. The nanoparticles are attracted to diseased cells. This allows treatment to take place and reduce damage to healthy cells. Nanotechnology in medicine can provide support in an event of impaired circulation by forming an "artificial red blood cell" which will improve the oxygen that is already available to the patient. Another way nanotechnology is used in medicine is in the flesh welder. This is when nano-shells are dribbled along a seam of skin. An infrared laser is then traced along the seam, causing the two sides to weld together. This can solve issues such as blood leaks during surgery.




 * __Sports__ attire is made with nanoparticles which create a shoe that will weigh less. The particles are light weight and increase strength. Although they are fairly thin, they will protect a player from a kick in the shin. The nanopatricle material are being used today in squash and badminton racquets,baseball bats, hockey sticks, snowboards, skis, fishing rods and poles, golf balls, and golf clubs.
 * The field of __Textiles__ puts nanotechnology to use in their consumer products. Nanoparticles are used to make products such as stain-resistant and anti-wrinkle sprays. One example of a recent application to textiles is in the shark-skin suit worn by Michael Phelps. It was designed to help the swimmer glide through water due to a plasma layer enhanced by nanotechnology to repel water molecule.


 * The __Food__ industry has incorporated the use of nanotechnology into their packaging. Bottles are commonly made with nano-composites that can minimize leakage of carbon dioxide, which increases its shelf life. In food storage bins, nanoparticles are embedded in the plastic which can kill bacteria from any food previously stored in the bins. There are also many products currently under development. One of these is the nanosensor which is in plastic packaging. The nanosensor can detect gases given off by food when it spoils. The package performs this by changing color to alert you that the food has gone bad. This sensor is even able to detect salmonella.





USES OF SILVER NANOPARTICLES
__antibacterial application__: Silver nanoparticles are incorporated into apparel, footwear, paints, wound dressings, appliances, cosmetics, and plastics for their antibacterial properties. Some examples of products that contain this are are filters, toys, pacifers, food storage, and dertergent. __diagnostic application:__ Silver nanoparticles are used in biosensors and other investigative procedures. __optical application:__ Silver nanoparticles are used to harvest light. They are also used for enhanced optical spectroscopes. __conductive application__: Silver nanoparticles are used in conductive inks and merged into materials to enhance thermal and electrical conductivity.

** DRAWBACKS OF NANOTECHNOLOGY **
Nanotechnology can sometimes kill the beneficial bacteria in the enviroment. There are genuine health concerns and toxicity regulations are difficult apply as the properties of nanomaterials depend on the size of particles.
