Nanoparticle - Wikipedia

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 At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead
