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, pH‐sensitive 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

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 ...

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 ...

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.

Monitoring of chicken meat freshness by means of a colorimetric sensor array
The Analyst, 2012A new optoelectronic nose to monitor chicken meat ageing has been developed. It is based on 16 pigments prepared by the incorporation of different dyes (pH indicators, Lewis acids, hydrogen-bonding derivatives, selective probes and natural dyes) into inorganic materials (UVM-7, silica and alumina).

An Optoelectronic Nose:“Seeing” Smells by Means of Colorimetric Sensor Arrays
MRS Bulletin, 2004AbstractA new approach to general sensors for odors and volatile organic compounds (VOCs) using thin films of chemically responsive dyes as a colorimetric sensor array is described. This optoelectronic “nose,” by using an array of multiple dyes whose colors change based on the full range of intermolecular interactions, provides enormous discriminatory ...
