There have been recent reports on photonic gel sensors, fabricated using an artificial opal templating method, that rely on reversible changes in the reflective color in response to the binding of the analyte to the receptor tagged to the hydrogel. Two essential features of a photonic gel sensor are (1) the existence of external stimuli (either chemical or field) to induce a solvent influx and subsequent volume changes of the hydrogel, and (2) periodic variations of refractive indices within the opal-templated hydrogel at the submicron length scale exhibiting various reflective colors with specific stimuli. Since the reflective color originates from the periodic structure of the hydrogel, it is often called the structural color. In this presentation, we present an artificial opal platform technology for the fabrication of inverse opal photonic gel sensors exhibiting fast responses to various stimuli. Recent developments of photonic gel sensors from two different fabrication approaches of photonic film and photonic ball will be discussed.
