5. Although thiolate-stabilized nanoparticles have received much attention in the past few years, passivation by amine-terminated molecules has remained largely unexplored. A significant problem has been that the preparative method popularized by Brust et al. leads to highly size-disperse nanoparticles when adapted to induce passivation by amines.
