Nanoparticle

Nanoparticles are important in various engineering and industrial fields comprising engineering catalysts, advanced ceramics, electronics, new batteries, fundamental ink and paint, biotechnology, drug delivery system, etc., and makes use of the unique properties of nanoparticles, which are completely different from those of the bulk materials (ores, minerals, coal, cereals, woodchips, sand, gravel, clay, cement). The surface layer is an integral a part of Nano scale matter, fundamentally affecting all of its properties. The surface layer typically consists of ions, inorganic and organic molecules. In nanotechnology, a particle is defined as a little object that behaves as a whole unit with reference to its transport and properties. Particles are further classified according to diameter.
