One nanometer equals one billionth or 10-9 of a meter. A very tiny unit of length. Nanotechnology is a multidisciplinary field of applied sciences where scientists are trying to understand matter on atomic or molecular scale, a very fine level. Most probably the ultimate quantum level. The aim is to develop devices within that tiny range (1 to 100 nm). That means nanoproducts will be extremely tiny to our natural sight. The purpose is to benefit health and sustainable energy fields.
