Gallic acid (GA), widely used in food and medicine production industries. Herein, a kind of newly synthesized cobalt-nitrogen co-doped carbon dots (Co,N-CDs) with dual functional properties oxidase-like activity photoluminescence property could oxidize the 3,3',5,5'-tetramethylbenzidine (TMB) to oxTMB new absorption peak at 653 nm. In addition, it was found that performed fluorescence-quenching effect on Co,N-CDs 440 nm attributed FRET (Fluorescence resonance energy transfer). Reductive GA reduce TMB, weaken blue color, restore fluorescence Co,N-CDs. Thus, colorimetric fluorometric method for dual-mode detection established. The synthesis dual-signal probe completed single environmental precursor just one step. Simultaneously, reduced limits, broadened linear range improved anti-interference ability. This exhibited satisfactory application prospect actual tea beverages.
