Popis:	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. Smart(phone) recognition: A new fluorescent sensor able to interact noncovalently with DMMP, a CWA simulant, has been synthetized and tested both in solution and in the gas phase. The detection limit in solution is much lower than the toxicity values of CWAs; in the gas phase sensing can be performed on a simple smartphone. With acid/base treatment, the solid device can be reused. This prototype paves the way for the smart detection of nerve agents.
