Chungang Wang and colleagues develop a new synthetic route to prepare gold nanostars (GNSs) with Fe₃O₄ cores under mild conditions. The result is an easy way to obtain magnetic GNSs with tunable optical properties from the visible to near-infrared. Even more, the particles described also show catalytic activity and can be easily recycled using an external magnet.
