What is a Nano Technology?

Nano technology is the engineering of functional systems with a very small size that has the ability to produce sophisticated and modern.

  

Nano technology is generating a revolution in the field of manufacturing and implications for social, economic and environmental.

 One nanometer is a billionth of a meter, or can be said to be equal to the area three or four atoms.
Nano technology in addition to providing great benefits for humans in various fields but also can bring great danger.

This is because the elements are made ​​of a very small size will have different properties with normal-sized elements so that these elements can react to the environment in unpredictable ways.
With nano technology, the resulting product will have a much better quality, more durable, safer, more efficient, cleaner and more efficient, better for communication, medicine, transportation, agriculture and industry.

One of the applications of nanotechnologies in medicine which carried out the development of nano-sized drug particles so that the drug can directly regarding cell disease in the body.

 
If it has been perfected, this method can reduce the adverse effects of chemotherapy that can damage healthy cells. While in the fields of electronics, nanotechnology can increase the capabilities of electronic devices with reduced power consumption and weight of the product.

 
Nanotechnology also have an impact on several aspects of food technology. Food companies to develop nano-sized materials that not only make a difference in the taste of food but also the safety and health benefits.

  In addition, nano technology is also used in order to save the cost of fuel catalysts used in fuel cells to produce hydrogen ions from fuels such as methanol and to improve the efficiency of the membrane or coating that is used in fuel cells to separate hydrogen ions from other gases such as oxygen.
Many companies are now developing batteries using nano-sized materials. Batteries with this material will be durable even if stored for many years and can be recharged faster than conventional batteries.
  For the environment, nanotechnology can improve the performance of catalysts used to convert the gas that comes out of the car or the factory into harmless gases. This is because the catalyst is made from nanoscale particles have a surface area that is far more likely to react with chemicals than catalysts made ​​from large particles.

  The greater the surface area the more chemicals that interact with the catalyst so that the catalyst is more effective. In addition, nanotechnology is now also widely used as a solution to the problem of water pollution such as waste disposal plant.

  Nanotechnology can be used to alter the chemical substances contaminated by a chemical reaction into harmless substances.
