Agile Detection of Chemical Warfare Agents by Machine Vision: a Supramolecular Approach
Nunzio Tuccitto, G Catania, Andrea Pappalardo, Giuseppe Trusso Sfrazzetto
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.
