A dual-ratiometric fluorescent probe for individual and continuous detection of HS and HClO in living cells.

HClO and H2S are crucial for maintaining the homeostasis in cells and play vital roles in many physiological and pathological processes. Herein, we present a fluorescent probe that can respectively and simultaneously detect H2S and HClO in a dual-ratiometric manner with good linearity. Utilizing this probe, the imaging of intracellular H2S or/and HClO in living cells in a ratiometric manner was achieved.
