Polymer-stabilized gold nanoparticles with high grafting densities.
A series of polymer-coated Au nanoparticles have been prepared using the "grafting-to" approach. Thiol-terminated polystyrene and poly(ethylene oxide) ligands are found to form dense brushes on the faceted gold nanoparticle surfaces. Depending on the polymer, the ligand grafting densities on the gold nanoparticles are 1.2- to 23.5-fold greater than those available via self-assembled monolayer formation of the corresponding two-dimensional gold surfaces.
