NANO TECHNOLOGY: BENEFITS AND RISKS

Nano technology is micro in size but large in usages. Nano technology is scaled in nano meter but its effective field is very large. As due to revolution in information technology and communication field, world has changed thoroughly, same as, nano technology is also considered as an ‘Age-changer' technology. It will affect on science, business, engineering, medical, electronics, defense and day to day technology. It is believed that Nano technology is in its infant stage right now, but up to 2025 it will be developed fully. Specially, Nano technology is of atomic scale, so, Newton's motion law of physical object can't be applicable to it. But it follows the rules of Quantum mechanics. Because of this reason scientists are excited, and they believe that through Nano technology, it has been possible to work at atomic scale and so it is useful in many ways. With the help of Nano technology, we can work at atomic scale. This is the main plus point of Nano technology. But we evaluate this point on the basis of its limitations, we will be shocked. An unexpected deficiency when we work on DNA is only due to Nano technology or terrorist spy about county's defense system with the help of Nano technology. It is really shocking. Seeing the glittering uses of Nano technology, we should not neglect its risk factors. Today we haven't proper guideline how to use Nano technology. At this time our blind run behind Nano technology may be so dangerous for environment and humanity that we will not be able to repay for this till centuries.
