Lower Detection

A water-soluble fluorescent probe was described for detecting hydrogen peroxide with the carbazole-derived as fluorophore and boronate moiety as recognition unit. The probe was developed as a turn-off fluorescent chemosensor with fast, high selectivity and sensitivity toward H2O2over other biological reactive oxygen species. What is more, the probe was quenched linear response to H2O2concentration in the range of 1.0×10−8- 2.0×10−5M and lower detection limit down to 6 nM (S / N = 3) was obtained.
