Encapsulation and Growth of Gold Nanoparticles in Thermoresponsive Microgels

Gold nanoparticles are encapsulatedwithin thermoresponsive pNIPAMmigrogels through an easy two-stepprotocol. The core/shell structure ofthe composite is characterized by TEM,AFM, PCS, and UV-vis spectroscopy. The restricted environment and thehigh porosity of the microgel shell arestudied through the overgrowth of thegold core.
