Abstract
The state of the art of colorimetric and fluorometric sensor arrays is reviewed. Sensor arrays based on chemically responsive colorants (dyes and nanoporous pigments) can be used to probe the chemical reactivity of analytes, rather than their physical properties, and provide a means to identify single component analytes or complex mixtures. The sensor array generates a high-dimensional response for chemical sensing that permits high sensitivity (often down to ppb levels), impressive discrimination among very similar analytes, and exquisite fingerprinting of extremely similar mixtures over a wide range of analyte types, both in the gas and liquid phases. This comprehensive article presents the recent progress in colorimetric and fluorometric sensor arrays, examines the methods of analysis of the high-dimensional data so obtained, and describes a wide range of applications.
