Thermoresponsive microgels have been shown to be an excellent platform for designing sensor materials. Recently, poly (N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgel based etalon materials have been described as direct sensing materials that can be designed to have a single, unique color. These color tunable materials show immense promise for sensing due ...
