A near-infrared reversible and ratiometric fluorescent probe based on Se-BODIPY for the redox cycle mediated by hypobromous acid and hydrogen sulfide in living cells

摘要

We have developed a near-infrared (NIR) reversible and ratiometric fluorescence sensor based on Se-BODIPY for the redox cycle between hypobromous acid oxidative stress and hydrogen sulfide repair. Real-time imaging shows that the probe is able to monitor intracellular HBrO/H_2S redox cycle replacement.
