What is Chemical Sensors: Optical Gas Sensors about?

Chemical sensing seeks to probe physical or chemical properties of chemical species and transform that into a useful and distinguishable output. The olfactory system of animals is the prototype of chemical sensing. Optical sensors are one of the most popular classes of chemical sensors, which use various forms of light-matter interactions to detect and interrogate chemicals of interest. The optically chemical sensors mainly include pH responsive dyes, Lewis acid indicators, redox dyes, solvatochromics, and aggregation-induced pigments. In analogy to olfaction, array-based optical sensor such as colorimetric sensor arrays provide high dimensional data from the color changes of chemically responsive colorants as they are exposed to analytes. Such colorimetric arrays probe a wide range of the chemical reactivity of analytes, rather than the limited dimensionality of physical properties.
