1.  The nanomaterials are particles in the size of 1 to 100 nanomters, equivalent to a billionth part of a meter The nanomaterials are divided in three categories: Nanoparticles Nanoplates Nanocomponents
2.  Nanoparticles are mostly used in the medical area. The nanoparticles for instances are used to find diseases in human body. Another use for the nanoparticles are the reactivation of some of the cells in the brain and help the doctors to health diseases like Parkinson. Aluminum nanooxide Fulleren nanocrystals
3.  Here are some names of the nanoparticles that exist in the market already: Doped Zinc Oxides, Mixed Rare Earth Metal oxides, NanoArcTM Bismuth Oxide, NanoArcTM Cerium oxide SGH, NanoArcTM Copper oxide, NanoDurTM Aluminum oxide, NanoGard, LL Zinc oxide, USP, NanoGard Zinc oxide, USP, Nanophase Zinc oxide NanoTek Aluminum oxide. Illustrated are scanning electron micrographs of cleansed elemental selenium formed by bacteria (A-C) or synthesized chemically (D and E). Metallic nanooxide
4. Carbon nanotubes The definition of the nano components materials: are materials that are made based on different components “nano metric scale worked” . For instance, take nano clay, to reinforce plastics, Carbon Nano tubes as well are used to provide conductivity to another materials.
