Microgels are sub-micron to micron-size polymeric networks confined in limited space swollen by a good solvent, also called hydrogel microparticles or microspheres if swollen in water. Among all microgels investigated nowadays, poly(N-isopropylacrylamide), pNIPAm, microgels are one of the most extensively studied microgel particles due to their volume phase transition (VPT) at lower critical solution temperature (LCST). By incorporation of pH-responsive monomer, acrylic acid (AAc), copolymeric pNIPAm-AAc microgels further demonstrate multi-responsivity to temperature, pH, and ionic strength....
