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.
