Abstract

Deposition under control: Silica nanoparticles with finely controllable size and surface charge were synthesized under benign conditions. By adjusting the electrostatic interactions, the silica nanoparticles can be assembled onto inorganic and biological surfaces in a controllable fashion. Potential uses for cell encapsulation are demonstrated.
