Nanotechnology is the field of research and innovation related with building ‘things’ - generally, materials and devices - on the size of atoms and molecules. A nanometre is a billionth of a metre: ten times the diameter of a proton. The diameter of a person’s hair is averagely , 80,000 nanometers. At such scales, the standard rules of physics and chemistry not apply. as an example , materials' characteristics, like their colour, strength, conductivity and reactivity, can differ dramatically between the nanoscale and therefore the macro. Carbon ‘nanotubes’ are 100 times stronger than steel but six fold lighter.

Nanotechnology is a group of all technologies and related Science used and studies in 1 to 100 nano , in the field of applied Science. Nano means materials that are made up of super-sized elements. Nanotechnology is the engineering of molecules and atoms, which combines subjects such as Physics, Chemistry, bio-informatics and biotechnology.
