The formation of Ag nanoparticles on polystyrene microspheres coated with poly( N ‐isopropylacrylamide) (PNIPAAm) is reported. It is shown that well‐dispersed Ag nanoparticles are formed in situ on the surface of the microspheres (see Figure). The surface‐grafted PNIPAAm chains are concluded to not only serve as steric stabilizers but also promote adsorption of the Ag nanoparticles.
