Among various types of chemical sensors, recently developed photonic crystal hydrogel sensor enables a simple detection by naked eye due to structural color changes of the sensor induced by binding of analyte to the sensor. In this study, we fabricated the Inverse opal (IO) structured Photonic crystal hydrogel chemical sensors by photopolymerization of various sensing monomers within the colloidal crystal template. In this presentation, various hydrogel IO sensors will be introduced showing fast response and selective color changes by various stimuli such as pH, temperature, ions, etc. |
