Sensors: Colorimetric Detection of Warfare Gases by Polydiacetylenes Toward Equipment-Free Detection (Adv. Funct. Mater. 8/2012)
On page 1632, Jinsang Kim and co-workers report the investigation of polydiacetylene (PDA) liposomes for equipment-free detection of warfare agents. The optimized oxime-modified PDA (OX-PDA) liposome in the solid state shows a selective and rapid optical transition upon exposure to as little as 160 ppb of diisopropylfluorophosphate (DFP), a nerve agent simulant. The results provide an insightful molecular design principle for PDA-based colorimetric sensors and suggest portable sensory patches for rapid, selective, sensitive, and convenient colorimetric detection of organophosphate nerve agents.
