Abstract

Nanoparticles are particles with a characteristic dimension below 100 nm. The properties of nanoparticles differ substantially from those of “big” colloidal particles (size bigger than 1 m) because radius of surface forces, which is around 100 nm, is greater than or comparable with the nanoparticles...
