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.

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 ...

Colorimetric Sensor Array for Qualitative Water Analysis
Australian Journal of Chemistry, 2009A chemosensor array comprising 45 off-the-shelf colorimetric dyes, dubbed the Singapore Tongue (SGT), that is capable of discriminating different brands of bottled water and waters of different geographical attribute is described. Twelve kinds of bottled waters were tested by the SGT, and changes of absorbance spectra were analyzed by unsupervised ...

Development of a colorimetric sensor Array for the discrimination of aldehydes
Sensors and Actuators B: Chemical, 2014Abstract A brand-new colorimetric sensor array was developed based on cross-reactive mechanism to discriminate 9 kinds of aldehydes and 16 volatile organic lung cancer biomarker candidates in low concentration. Sixteen out of twenty-seven dyes were selected to mix with 2,4-dinitrophenylhydrazine (DNPH) in optimized concentration to serve as specific ...

A colorimetric sensor array based on natural pigments for the discrimination of saccharides
Luminescence, 2020AbstractA colorimetric sensor array based on natural pigments was developed to discriminate between various saccharides. Anthocyanins, pHâsensitive natural pigments, were extracted from fruits and flowers and used as components of the sensor array. Variation in pH, due to the reaction between saccharides and boronic acids, caused obvious colour changes

Colorimetric Sensor Array for Determination and Identification of Toxic Industrial Chemicals
Analytical Chemistry, 2010A 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 with analytes.
