Colorimetric Sensor Array for Monitoring CO and Ethylene
Analytical Chemistry, 2018Developing miniaturized and inexpensive detectors remains an important and practical goal for field-deployable monitoring of toxic gases and other bioactive volatiles. CO (a common toxic pollutant) and ethylene (the phytohormone primarily responsible for fruit ripening) share the capability of strong back-π-bonding to low-oxidation-state metal ions ...

Detection of Chemical Warfare Agents by Colorimetric Sensor Arrays
ACS Sensors, 2020We report the successful use of colorimetric arrays to identify chemical warfare agents (CWAs). Methods were developed to interpret and analyze a 73-indicator array with an entirely automated workflow. Using a cross-validated first-nearest-neighbor algorithm for assessing detection and identification performances on 632 exposures, at 30 min ...

The Optoelectronic Nose: Colorimetric and Fluorometric Sensor Arrays
Chemical Reviews, 2018A comprehensive review on the development and state of the art of colorimetric and fluorometric sensor arrays is presented. Chemical sensing aims to detect subtle changes in the chemical environment by transforming relevant chemical or physical properties of molecular or ionic species (i.e., analytes) into an analytically useful output.

Colorimetric Sensor Array Reader System Using Smartphone Camera
ECS Meeting Abstracts, 2020Colorimetric sensor arrays were developed to detect gas molecules by changing colors a decade ago.[1] Since the colors of the sensors change while specific gas molecules interact with an array of the colorimetric chemical sensor, the technique for measuring and analyzing the changes of the colors upon gas interactions is very important.

A Colorimetric Sensor Array for Organics in Water
Journal of the American Chemical Society, 2005Molecular recognition of organic compounds in aqueous solutions is inherently challenging due to the potential interference from the very high concentration of water. Here we present a simple colorimetric sensor array that probes a wide range of chemical properties.
