Cyclodextrin-Based Metal-Organic Nanotube as Fluorescent Probe for Selective Turn-On Detection of Hydrogen Sulfide in Living Cells Based on H2S-Involved Coordination Mechanism
A new ESIPT based fluorescent H2S probe was developed, which exhibited ideal properties such as large turn on fluorescence signal, good selectivity, and it was suitable for visualization of exogenous and endogenous H2S in living cells.
Herein, we described a probe for H2S detection based on the reduction of azide to amine. This probe was highly sensitive and selective toward H2S and successfully applied for H2S fluorescent imaging in living cells.
