A method and apparatus is provided for the modification of the surface chemistry of solid nano- and micro-particles in order to tailor the properties and functions of these particles. The method generally involves the generation of an atmospheric plasma glow discharge and energetic species that undergo chemical reaction with the surface of the primary particles. The process includes the generation of energetic species to initiate reaction, optional delivery of a precursor fluid, optional delivery of chemical species for grafting, and delivery of separated and de-agglomerated particles into the plasma discharge exiting the plasma generation chamber.
