Apr 12, 2003 The pre- and post-particle data are compared to determine the cleanliness of the part(s). Another distinct factor that can affect the measurement concerns the bonding forces of the particles to the surface. Particles below 1.0 micron are already difficult to remove and when electrostatic charge is present, few, if any, particles from the

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.
