Test strips that in combination with a portable fluorescence reader or digital camera can rapidly and selectively detect chemical warfare agents (CWAs) such as Tabun (GA), Sarin (GB), and Soman (GD) and their simulants in the gas phase have been developed. The strips contain spots of a hybrid indicator material consisting of a fluorescent BODIPY indicator covalently anchored into the channels of mesoporous SBA silica microparticles. The fluorescence quenching response allows the sensitive detection of CWAs in the mu g m(-3) range in a few seconds. ; Financial support from the Alexander von Humboldt Foundation, the German Federal Ministry for Economic Affairs and Energy, European FEDER funds (MAT2012-38429-C04), the Generalitat Valenciana (PROMETEOII/2014/047), and the Spanish Government is gratefully acknowledged.
