Colorimetric plasmon resonance microfluidics on nanohole array sensors
Sensing and Bio-Sensing Research, 2015 We present the label-free colorimetric visualization in microfluidics using plasmon resonance on a large-area and over a wide field-of-view (>100 mm2) nanohole array device called nanoLycurgus Cup Array (nanoLCA).

Preoxidation for colorimetric sensor array detection of VOCs. [PDF]
J Am Chem Soc, 2011 A disposable preoxidation technique that dramatically improves the detection and identification of volatile organic compounds (VOCs) by a colorimetric sensor array is reported. Passing a vapor stream through a tube packed with chromic acid on silica immediately before the colorimetric sensor array substantially increases the sensitivity to less ...

MATRIX DISCRIMINANT ANALYSIS WITH APPLICATION TO COLORIMETRIC SENSOR ARRAY DATA. [PDF]
Technometrics, 2015 With the rapid development of nano-technology, a "colorimetric sensor array" (CSA) which is referred to as an optical electronic nose has been developed for the identification of toxicants. Unlike traditional sensors which rely on a single chemical interaction, CSA can measure multiple chemical interactions by using chemo-responsive dyes.
