A dual-responsive nanogel, poly(N-isopropylacrylamide)-co-poly(N,N-(dimethylamino)ethyl methacrylate) [P(NIPAM-co-DMA)] containing N-isopropylacrylamide (NIPAM) as thermoresponsive monomer and N,N-(dimethylamino)ethyl methacrylate (DMA) as pH-responsive monomer and methylene-bis-acrylamide (MBA) as cross-linking agent, was synthesized by free radical emulsion polymerization.
