Chemical warfare agents (CWAs) are highly toxic compounds capable of causing mass casualties on the battlefield. Current analytical methods for detecting blister, nerve, and blood agents suffer from several inherent limitations, including false-positive results, high costs, susceptibility to environmental interferences and cross-contamination, and relatively cumbersome sample pretreatment and operational procedures. In this work, the authors report the design and synthesis of TrioAlert, a fluorescent sensor capable of simultaneously detecting the blister agent sulfur mustard, the G-type nerve agent sarin, and the blood agent cyanide within 90 s.
