"Nanotechnology" is a generic term that describes applications in many scientific areas but covers a general research principles and existing properties at the nanoscale, that is to say at the level of atoms and molecules. The objective is to produce nanotechnology objects or materials of less than 100 nanometers.These nanomaterials are composed of nanoparticles, in contrast to fine natural or from a combustion particles are produced intentionally. Nanomaterials can be metals, ceramics, carbon, polymers or silicates which have the advantage of having specific characteristics compared to the same material at the macroscopic scale. The acquisition of these new physico-chemical properties and opens a whole range of basic and applied research grouped under the name of "nanoscience".
