Nanoparticle Wikipedia

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. Nanoparticles are usually distinguished from "fine particles", sized between 100 and 2500 nm, and "coarse
