Nanotechnology involves the manipulation of materials at the scale of the nanometer, one billionth of a meter. Some scientists believe that mastery of this subject is forthcoming that will transform the way that everything in the world is manufactured. Green nanotechnology is the mainly applicable to green chemistry and green engineering principles to this field. It has been described as the development of clean technologies, to minimize potential environmental and human health risks associated with the manufacture and use of nanotechnology products. Nano-products that is more environmentally friendly throughout their lifecycle.
