Reactive Arrays of Colorimetric Sensors for Metabolite and Steroid Identification

Journal of Sensor Technology, 2014
The work described herein examines a rapid mix-and-measure method called DETECHIP suitable for screening of steroids and metabolites. The addition of steroids and metabolites to reactive arrays of colorimetric sensors generated characteristic color "fingerprints" that were used to identify the analyte.

Colorimetric Protein Sensing Using Catalytically Amplified Sensor Arrays [PDF]

Small, 2012
Catalytically active iron oxide nanoparticles are used as recognition elements and signal amplifiers for the array-based colorimetric sensing of proteins. Interactions between cationic monolayers on the Fe(3) O(4) NPs and analyte proteins differentially modulates the peroxidase-like activity of Fe(3) O(4) NPs, affording catalytically amplified ...

Colorimetric Sensor Arrays for the Detection and Identification of Chemical Weapons and Explosives [PDF]

Critical Reviews in Analytical Chemistry, 2016
There is a significant demand for devices that can rapidly detect chemical-biological-explosive (CBE) threats on-site and allow for immediate responders to mitigate spread, risk, and loss. The key to an effective reconnaissance mission is a unified detection technology that analyzes potential threats in real time.
