Abstract
The synthesis and characterization of mechanically robust, optically tunable inverse opal hydrogel through colloidal crystal templating is presented. Mesoporous hydrogels based on HEMA-AA copolymers exhibit pH-dependent shifts in optical diffraction, the magnitude of which can be tailored by varying the AA concentration. In addition, such hydrogel also demonstrate ionic-strength-sensitive diffraction corresponding to both Donnan potential-induced welling and nonspecific polymer-water interactions.
