We report here a simple one-step protocol for the prepn. of near-monodisperse gold hydrosols in the small size regime (<5 nm). The particle size can be controlled by varying the concn. of the stabilizing polymer, which can be readily displaced by thiol ligands to yield monolayer protected clusters of the usual type.
