- Utilizing the wettability of inverse opal hydrogels, we report a new strategy to construct photonic hydrogels with multiple types of reliable signals, such as non-wetting (transparent), image contrast (weak color) with shifts of diffraction maximum (bright color), developing optical sensors for multifunctional detection.
