展示了反蛋白石水凝胶传感器的合成、溶胀动力学和光学衍射(见图)。胶体晶体模板用于制备具有相互连接的孔结构的甲基丙烯酸酯/丙烯酸(AA)共聚物，允许容易扩散和相对快速的响应。该体系表现出良好的机械稳定性和随pH变化的光学衍射峰随AA浓度的变化。
The synthesis, swelling kinetics, and optical diffraction of inverse opal hydrogel sensors(see Figure) are demonstrated. Colloidal crystal templating is used to prepare methacrylate/acrylic acid (AA) copolymers that have an interconnected pore structure, allowing facile diffusion and a relatively rapid response. The system shows good mechanical stability and pH‐dependent shifts in optical diffraction regulated by the AA concentration.
