摘要: Poly (N-isopropylacrylamide) (pNIPAm)-based hydrogels and hydrogel particles (microgels) have been extensively studied since their discovery "popularization" a few decades ago. While uses seem to no bounds, this Feature Article is focused on development application for sensing small molecules, macromolecules, biomolecules. Hydrogel/microgel-based photonic materials with order in one, two, or three dimensions are highlighted, which exhibit optical properties that depend the presence concentration of various analytes.
