NanoparticleWikipedia

A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles up to 500 nm citation needed or fibers and tubes that are less than 100 nm in only two directions. At the lowest range metal particles smaller than 1 nm are usually called atom clusters instead.
