A colorimetric sensor array-based classification of coffees
Sensors and Actuators B: Chemical, 2018Abstract A method based on colorimetric sensor array (CSA) was used to classify different coffees. The array was fabricated by printing twelve sensing materials selective to key coffee aroma odorants on a hydrophobic membrane. The unique color profile for each coffee sample was obtained, resulting in facile differentiation by the naked eye without ...

A Colorimetric Sensor Array for Detection of Triacetone Triperoxide Vapor
Journal of the American Chemical Society, 2010Triacetone triperoxide (TATP), one of the most dangerous primary explosives, has emerged as an explosive of choice for terrorists in recent years. Owing to the lack of UV absorbance, fluorescence, or facile ionization, TATP is extremely difficult to detect directly.

Monitoring vinegar acetic fermentation using a colorimetric sensor array
Sensors and Actuators B: Chemical, 2013Abstract This paper attempted a portable colorimetric sensor array to monitor vinegar acetic fermentation. We fabricated a colorimetric sensor array by printing 15 chemically responsive dyes (i.e. 9 porphyrins/metalloporphyrins and 6 pH indicators) on a C2 reverse silica-gel flat plate.

Colorimetric sensor arrays: Interplay of geometry, substrate and immobilization
Sensors and Actuators B: Chemical, 2014Abstract This study addresses the interplay of geometry, substrate, and dye immobilization method on colorimetric sensor array performance. Arrays of cross-responsive dyes were exposed to either ammonia or sulfur dioxide gas at their permissible exposure levels (PEL) or their immediately dangerous to life or health (IDLH) concentrations and their ...
