What is nanotechnology?

Nanotechnology is the engineering of function systems at molecular scale. In other words it is the manipulation of matter on the molecular scale. The size of a nano material is of the order of nano meter, that is 10-9 of a meter. In a material perspective ,it is larger to smaller and in molecular perspective, it is simple to complex.

 

How does nano technology help us ?

Almost all nations have invested heavily in nanotechnology because it helps in developing raw materials with dimensions on the nano scale. It helps in various fields of science such as molecular biology, semi conductor physics, microfabrication,etc. Medicine, electronics,energy productions are helped in a vast scale.

Originally when the word “nanotechnology” was coined in the 1980s, it was meant to building machines on the scale of molecules.

 

Richard Feynman,Nobel prize winner in Physics, had a vision to build miniature factories using nano machines to build complex products. This will result in a manufacturing revolution. It will also help in making high quality products at a very low cost and rapid speed.

However, it also raises concerns about the toxicity and environmental impact of nano materials.
