Abstract
The science behind nanotechnology is understanding the control of matter at nano-scale. Nano, prefix denoting a factor of 10-9 i.e. material possessing grain sizes in the order of one billionth of a meter. Word nano has its origin in Greek meaning dwarf. When characteristic length scale of microstructure is in the range of 1-100nm. exhibit unique properties and provides opportunity to use nano-materials in novel applications and devices. Nanotechnology is the design, characterization production and application of structures, devices and the system based upon individual or multiple integrated nano-scale components. Nanomaterials have been used over a millennium, example nanoscale gold was used in stained glass in medieval Europe and nano-tubes were found in the blades of swords made in Damuscus. Nano-materials contain nanoscale structures internally or on their surfaces. These can include engineered nano objects, such as nanoparticles, nanotubes and nanoplates. Volcanic ash, sea-spray, smoke from fire and exhaust of vehicles are naturally occurring nanoparticles. Nanotechnology is used in many commercial products and holds great potential in future Keywords— Nanoscale, Nanoparticles and Nanomaterial.
