PREPARATION OF STABLE HIGH CONCENTRATION COLLOIDAL METAL PARTICULATE SYSTEMS |
摘要 |
<p>Gold suspensions with high concentrations of gold, and silver suspensions with high concentrations of silver, are provided. Gold or silver nanoparticles are put into suspension, where the metal nanoparticles are paired with silica. Biocompatible suspensions are one application. Noble metal particles, attached to the surface of silica particles, form a stable, non-agglomerated suspension due to the steric and repulsive properties of the silica particles. The noble metal particles are prepared by activating the surface of the silica particles and erecting nucleation sites for metal particle growth, and then growing the metal particles at the nucleation sites through a reduction procedure.</p> |
