Rapid determination of fish freshness using colorimetric sensor array
2010 Pittsburgh, Pennsylvania, June 20 - June 23, 2010, 2010Freshness is the most important factor in fish quality evaluation. This research was intended to develop an artificial olfaction system based on colorimetric sensor array for rapid evaluation of fish freshness. Nine chemically responsive dyes including metalloporphyrins and pH indicator were selected according to their sensitivity to volatile compounds

Antioxidants Recognition Colorimetric Sensor Array Based on Multicolor System
Applied Organometallic ChemistryABSTRACTA colorimetric sensor array with three identification signals has been developed to visually recognize five antioxidants based on CuFe Prussian blue analogs nanocubes (CuFe PBA NCs) and 3,3′,5,5′‐tetramethylbenzidine (TMB). The CuFe PBA NCs can oxidize TMB to produce three ultraviolet–visible (UV–Vis) absorption peaks at different wavelengths ...
