One-step synthesis of S, B co-doped carbon dots and application for selective and sensitive fluorescent detection of diethylstilbestrol

Abstract

Here, we report a fast and selective technique for the determination of diethylstilbestrol in milk sample by using fluorescent sulfur and boron co-doped carbon dots (S, B co-doped CDs).The S, B co-doped CDs were synthesized by hydrothermal synthesis using poly (sodium-p-styrenesulfonate) and borax as precursor. The as-prepared S, B co-doped CDs possess good stability, fluorescence characteristics and show a quantum yield of 25.7%, which is the result of the existence of sulfur and boron atoms among CDs. The fluorescence intensity of the S, B co-doped CDs decreased in the presence of diethylstilbestrol, and exhibits a good linear relationship between the fluorescence quenching and different concentration of diethylstilbestrol in range of 0.1-200 μM with a detection limit of 0.06 μM. Finally, the S, B co-doped CDs have been successfully applied in the detection of diethylstilbestrol in milk samples, yielding recoveries between 90.4% and 109.2%.
