A two-photon ratiometric fluorescent probe for highly selective sensing of mitochondrial cysteine in live cells

Abstract

We report a novel two-photon ratiometric fluorescent probe (DNEPI) for highly selective sensing mitochondrial Cys in live cells.

A molecular design towards sulfonyl aza-BODIPY based NIR fluorescent and colorimetric probe for selective cysteine detection

“…S20 †), but the color of BDP-1 was unchanged in the highconcentration of Hcy (1 mM). [30][31][32] The color change of BDP-1 in the presence of Cys was conrmed by UV/vis absorption and uorescence emission spectra (Fig. S20 and S23 †).…”

Fluorescent probes based on nucleophilic aromatic substitution reactions for reactive sulfur and selenium species: Recent progress, applications, and design strategies

“…Benzenesulfonamide and benzenesulfonate are the main reactive groups of benzenesulfonic acid [20] , [112] , [113] , [114] , [115] , [116] , [117] , [118] , [119] , [120] . RSS and RSeS can break the benzenesulfonamide or benzenesulfonate bond and become bound to the aromatic part of the detection group with the concomitant release of SO 2 .…”

Reduced Thiol Compounds – Induced Biosensing, Bioimaging Analysis and Targeted Delivery

“…At the same time, due to the lack of tissue penetration depth, the application of biological imaging is greatly limited. Therefore, to solve the shortcomings of single‐ molecule fluorescent probes, research on bimolecular fluorescent probes has been carried out, as such probes would offer improved performance [39] …”

“…The mechanism of the bimolecular fluorescent probes studied previously was that ICT, leads to serious overlap between probes and the movement of emission bands, which greatly affects the accuracy and resolution of the detection results [6,8,15,39] . In order to solve this problem and improve the resolution of the fluorescent probe, Yang et al .…”
