Colorimetric Sensor Array: Do I See What You Smell
… a unique chemical detection technology in which colorimetric changes in an array of dyes constitute a signal much like that generated by the mammalian olfaction system; each dye is a cross-responsive sensor. This technology uses a disposable printed array of chemically responsive dyes as the …

Colorimetric sensor arrays with a pre-oxidation method for gaseous analytes
The Suslick group has developed a disposable colorimetric sensor array methodology for use as an optoelectronic nose that has been applied successfully for the identification of a wide range of both gases/vapors and analytes in aqueous liquids. These colorimetric sensor arrays, however, are …

Artificial and mammalian olfaction and low-coordinate metalloporphyrin complexes
Part 1 A low-cost yet highly sensitive colorimetric sensor array for the detection and identification of toxic industrial chemicals (TICs) has been developed. The sensor consists of a disposable array of cross-responsive nanoporous pigments whose colors are changed by diverse chemical interactions …

Silicone microspheres and disposable separation technology for gaseous analytes
… work also describes advancements in realizing colorimetric sensor arrays as microdetectors for gas chromatography. Because GC miniaturization necessitates extremely short columns (often < 3 m in total length), micro-GC systems suffer from incomplete separations and frequently have analytes …
