Outline of Final Research Achievements

By using NIPAM hydrogel containing silica colloidal particles, we have developed a chemical sensor that have micro-arrayed slimuli-responsive photonic colloidal crystal gels. The sensor displays color shift depending on concentration of target chemicals or its physical conditions because the hydrogel exhibits eye-visible structural colors. We succeeded in measuring ethanol concentration and temperature at the same time by using the proposed hydrogel microarray sensor.
