Impact of nanotechnology in society

Abstract

Nanotechnology is the term used in those areas and sections of science and engineering where we study at dimensions and Nano level. The word nano means 10^–9 which is a very low value. With the term of nanotechnology scientists can modify molecules, atoms, human body cells and food components at dimension level. Nanotechnology is the science of manipulation and engineering of matter, particles and structures on the nanometer scale (one millionth of a millimeter, the scale of atoms and molecules). Field of nanotechnology is very wide and today this emerging science has established a number of milestones in the field of environment, energy, defence, agriculture, food, chemical as well as pharmacy. With the help of nanotechnology scientists can modify the structure of nanoparticles and can see the dimensions of nanoparticles bigger than their sizes. This control at the nanoscale is divided by nanotechnology with another kind of technology.
