Hydrogel opals, exhibiting striking iridescence while being soft and gelatinous , can be synthesized by covalent bonding (through crosslinkers) of self‐assembled hydrogel nanoparticles, which consist of N ‐isopropyl‐acrylamide copolymers with reactive side groups. Beyond their aesthetic value (see Figure and also cover) hydrogel opals are potentially useful as thermo‐ or electrochromic gel sensors.
