Terpyridine-Lanthanide Complexes Respond to Fluorophosphate Containing Nerve Gas G-Agent Surrogates
Raja Shunmugam, Gregory N. Tew
The significant problem of nerve gas poisoning requires new methods of detection, which are sensitive and selective. A new G-type agent chemical sensor is reported that exploits terpyridine-lanthanide emission. A detection limit of 6 ppb is obtained and the selectivity for reactive surrogates over a variety of other close chemical analogs is demonstrated.
