Polysiloxane-based Mitochondria-Targeted fluorescent probe for the detection of endogenous and exogenous H2S in living cells

A human serum albumin-binding-based fluorescent probe for monitoring hydrogen sulfide and bioimaging

“…Recent investigations on fluorescent probes for H 2 S detection are listed in Table S1 † for comparison. [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] Although many probes have been reported to show high sensitivity and selectivity, the measurement span (linear range) values were relatively narrow and limited the practical applications. Herein, the optical capabilities of the probe TPABF-HS were tested, and the linear range was especially focussed on.…”

“…[22][23][24] The reported recognition mechanisms involve azide reduction, copper precipitation and nucleophilic attack on ethers, esters and double bonds, while the selected fluorophores include coumarin, rhodamine, naphthalimide and hemicyanine. [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] For evaluating the practical application of fluorescent probes, the key performance indicators include selectivity (anti-interference), sensitivity (limit of detection (LOD)) and measurement span (linear range).…”
