  • Organically-functionalized monodisperse nanocrystals of metals
    Patent number: 6103868
    Abstract: Organically functionalized metal nanoparticles are produced by mixing a metal precursor with an organic surface passivant and reacting the resulting mixture with a reducing agent to generate free metal while binding the passivant to the surface of the free metal to produce organically functionalized metal particles.
