A versatile approach to fabricate monodisperse poly[styrene‐ co ‐(divinyl benzene)] (PS‐ co ‐DVB) microcapsules that contain a single gold nanoparticle (AuNP) has been demonstrated. Using the PS‐ co ‐DVB microcapsule as a microreactor, aqueous HAuCl 4 and NaBH 4 solutions are subsequently infiltrated. The size of the resulting AuNP inside of the PS‐ co ‐DVB microcapsules is easily tunable by controlling the repeated infiltration cycles of aqueous HAuCl 4 and NaBH 4 . PS‐ co ‐DVB microcapsules that contain a single silver and palladium nanoparticle are also obtained by following a similar protocol.
