“…In this context, cationic surfactant cetyltrimethylammonium bromide (CTAB) has been utilized in the literature to enhance both the rate of the reaction and the intensity of the uorescence. 66,67 Based on this precedent, we successfully employed CTAB to enhance the reactivity of probe 6g in highly aqueous medium (0.5% DMSO in PBS).

“…Very recently, several other azide-based fluorescent probes have been developed, which include SS1 (a colorimetric probe), P1, Eu·2 (a luminescent probe), and P2 (a turn-off fluorescent probe with a NIR emission wavelength, Scheme 6). [61][62][63][64] It was found that surfactants such as hexadecyltrimethyl-ammonium bromide (CTAB) significantly enhance the sensitivity of the probes. [61,62]…”

Hydrogen sulfide (H 2 S) is an important signaling molecule with potent cytoprotective actions. Current results strongly suggest that modulation of H 2 S levels could have potential therapeutic values for a number of disease states, but its exact mechanisms of action are still unclear. A number of fundamental issues must be addressed to advance our understanding of the biology and clinical potential of H 2 S in the future. It is important, therefore, to understand the chemistry and properties of H 2 S and to appreciate the limitation and errors that may be generated when measuring H 2 S in biological samples. In the past several years a number of fluorescent probes for H 2 S detection have been developed. These probes are based on H 2 S-mediated reactions and are useful research tools. Herein, we provide an overview of current progress in this field. The development and properties of representative probes are discussed. Scheme 2.

“…It is different from traditional analytical methods; the advances in uorescent probes can sense H 2 S inside the living cells, particularly, transduce the nanoscale biochemical processes into optical signals. In the biology eld, based on the nucleophilic reaction, good reducibility towards azide compounds 29,30 and high binding affinity towards copper ions, [31][32][33] uorescent probes for hydrogen sulde are used. Moreover, it is difficult to design uorescent probes to sense H 2 S from other biological mercaptans (biological nucleophile).…”
