| Περίληψη: | Thiram residue has drawn widespread attention due to its severe threat to the agricultural safety. Herein, a ratiometric fluorescence probe was designed for thiram detection based on glutathione capped zinc nanoclusters (GSH-ZnNCs) and o-phenylenediamine (OPD). OPD was oxidized by Ag+ to produce 2, 3-diaminophenazine (DAP), and the fluorescence of GSH-ZnNCs was quenched by DAP through fluorescence resonance energy transfer (FRET) effect. When exposed to thiram, Ag+ led to the cleavage of SS bond in thiram to form Ag+-dimethyl thiocarbamate complex, inhibiting the oxidation of OPD. Accordingly, specific thiram detection was constructed with GSH-ZnNCs. The ratiometric fluorescence value of lg(I (Copyright © 2026 Elsevier Ltd. All rights reserved.) |
