Abstract:
A water-soluble fluorescent SO2 derivatives probe PI-SO 2 based on a phenanthroimidazole dye, and a sensitive SO2 recognition site, aldehyde was constructed. The probe PI-SO 2 exhibits desirable properties such as high sensitivity, high selectivity and good water-solubility. Significantly, we have demonstrated that the probe PI-SO 2 is suitable for rapidly fluorescence detecting of SO2 derivatives in aqueous solution and serum. The application of the novel probe PI-SO 2 proved that it was not only a useful tool for the detection of SO2 derivatives in vitro, but also a potential assay for investigating the effects of SO2 derivatives, and demonstrating its value in practical applicationin of complex biological samples.
