title: Spherical ensembles of gold nanoparticles on silica: electrostatic and size effects.
abstract: Core-shell ensembles of citrate-stabilized gold nanoparticles (20-80 nm) on submicron silica cores (330-550 nm) have been prepared by electrostatic self-assembly with shell packing densities as high as phi = 0.55.
