Colorimetric Sensor Arrays for Volatile Organic Compounds
Analytical Chemistry, 2006The development of a low-cost, sensitive colorimetric sensor array for the detection and identification of volatile organic compounds (VOCs) is reported. Using an array composed of chemoresponsive dyes, enormous discriminatory power is possible in a simple device that can be imaged easily with an ordinary flatbed scanner.

A colorimetric sensor array for odour visualization
Nature, 2000Array-based vapour-sensing devices are used to detect and differentiate between chemically diverse analytes. These systems--based on cross-responsive sensor elements--aim to mimic the mammalian olfactory system by producing composite responses unique to each odorant.

Counterion Free Colorimetric Metal Cation Sensor Array
Journal of Combinatorial Chemistry, 2007By a systematic ionic effect study in colorimetric dye arrays, we effectively suppressed the anion effect using the proper buffer condition and configured a universal cation sensor system. This result cast a warning for careful validation for other anion sensing systems in aqueous solution.

Hand-Held Reader for Colorimetric Sensor Arrays
Analytical Chemistry, 2015An inexpensive hand-held device for analysis of colorimetric sensor arrays (CSAs) has been developed. The device makes use of a contact image sensor (CIS), technology commonly used in business card scanners, to rapidly collect low-noise colorimetric data for chemical sensing. The lack of moving parts and insensitivity to vibration allow for lower noise

Colorimetric Sensor Array for Soft Drink Analysis
Journal of Agricultural and Food Chemistry, 2006Fourteen commercial soft drinks have been analyzed using colorimetric sensor arrays made from a set of 25 chemically responsive dyes printed on a hydrophobic membrane. Digital imaging of the dye array before and after immersion provides a color change profile as a unique fingerprint for each specific analyte.
