Abstract
A single step milling and surface coating process allows for production of a stable dispersion of surface coated nanoparticles in an efficient manner. The process comprises providing feed particles, providing a coating agent, and generating the stable dispersion of surface coated nanoparticles by milling the feed particles in an aqueous medium containing the coating agent such that the coating agent bonds to surfaces of the feed particles as the feed particles are milled to an average particle size of less than about 100 nm.
