Abstract

The invention describes a nanocomposite particle comprising a nanoparticle having a surface comprising a silver salt, and at least one region of metallic gold on said surface. The invention also provides a nanocomposite material comprising said particles and processes for making the nanocomposite material, either by allowing gold in nanoparticles having a silver salt on the surface thereof to at least partially diffuse through the silver salt so as to form at least one region of metallic gold on said surface, or else by depositing metallic gold on the surfaces of nanoparticles having the silver salt on the surface thereof.
