Local MPC of a poly(N,N-dimethyl acrylamide)-based copolymer with an anthraquinone crosslinker is shown via atomic force microscopy. Additionally, MPC is tested with a thermoresponsive poly(N-isopropyl acrylamide)-based terpolymer. The reversible thermal collapsing and swelling of the MPC-formed hydrogel at specific nanoparticle locations are confirmed by polarization-resolved LSPR spectroscopy. These hybrid metallic/hydrogel materials can be further post-modified offering attractive characteristics for future spectroscopic/bioanalytical applications.
