What is Nanotechnology?

Nanotechnology refers to the scientific field which deals in the research and creation of matter particles, which are very small in size – usually 100 nanometers or smaller-. For example, one nanometer (nm) is one billionth of a meter (10-9 m). it is so small that if earth was one meter in diameter, then one nanometer would have been the size of an apple. When a common material shrinks at nanoscale level, it exhibits genuine and unique properties compared to smaller molecules or larger conventional bulk materials.
