Nanocomposite hydrogels consisting of colloidal gold nanoparticles and thermoresponsive N ‐isopropylacrylamide copolymers (see Figure) are synthesized. The size, morphology, and stability of the nanoparticles are controlled by the amount of thiol group in the polymer side chains. Compared with non‐Au‐containing hydrogels, remarkably different bulk properties of equilibrium swelling and thermoresponsive phase transition are displayed.
