Abstract

Amine-functionalized mesoporous silica nanoparticles containing poly(p-phenylenevinylene) provide a facile strategy to detect TNT through fluorescence resonance energy transfer (FRET). The observed linear fluorescence intensity change allows the quantitative detection of TNT with the detection limit of 6 × 10(-7) M.
