In this study, hybrid SiO2 nanoparticles functionalized with 1,8-naphthalimide-pyridine were successfully prepared and used as a fluorescent film probe for detecting nerve agent simulants. The probe showed highly selective fluorescence turn-on signals for nerve agent simulants and effectively discriminated false-positive interferences from mineral acids by their fluorescence turn-off response. This study demonstrates a novel platform for detecting various nerve agent simulants and provides an effective strategy for distinguishing between nerve agent simulants and acids.
Here, 1,8-naphthalimide-pyridine functionalized hybrid SiO2 nanoparticles (SiO2 NPs) are successfully prepared and applied as the fluorescent film probe for Organophosphorus (OP)-based nerve agent (Sarin, Soman and Tabun) simulants. By using this novel fluorescent film probe, not only the highly selective fluorescence turn-on signals for nerve agent simulants are obtained, but also the bedeviling false-positive interferences mineral acids are discriminated exhaustively by their fluorescence turn-off response. Hereby, this study demonstrates a novel platform for multiform nerve agent simulants detection and provide an effective strategy for the identification between nerve agent simulants and acids.
