Agile Detection of Chemical Warfare Agents by Machine Vision: a Supramolecular Approach

Chemistry. 2021 Oct 1;27(55):13715-13718. doi: 10.1002/chem.202102094. Epub 2021 Aug 20.

Abstract

The supramolecular detection by image analysis of a simulant chemical warfare agent on a solid device containing a selective molecular sensor based on a BODIPY scaffold is reported. The recognition properties were investigated in solution, demonstrating high affinity (log K 6.60) and sensitivity (LOD 10 ppt). A test strip also confirmed the sensing properties in gas phase. Image analysis of the solid device allows quantitative information about the simulant to be obtained, recovering the sensor almost 5 times and thus confirming the goal of the supramolecular approach.
