Fast responding and selective near-IR Bodipy dye for hydrogen sulfide sensing.
نویسندگان
چکیده
A Bodipy based, highly selective probe for hydrogen sulfide has been designed, synthesized and demonstrated to detect H2S in living cells. In this design, the reduction of two arylazido groups change the charge transfer characteristics of the 3,5-distyryl substituents on the Bodipy core, producing a 20 nm bathochromic spectral shift in the absorption band, and quenching of the emission by 85% compared to the original intensity, through photoinduced electron transfer.

A near-infrared reversible and ratiometric fluorescent probe based on Se-BODIPY for the redox cycle mediated by hypobromous acid and hydrogen sulfide in living cells.
We have developed a near-infrared (NIR) reversible and ratiometric fluorescence sensor based on Se-BODIPY for the redox cycle between hypobromous acid oxidative stress and hydrogen sulfide repair. Real-time imaging shows that the probe is able to monitor intracellular HBrO/H2S redox cycle replacement.
متن کاملA near-infrared fluorescent probe for the detection of hydrogen polysulfides biosynthetic pathways in living cells and in vivo.
Hydrogen polysulfides (H2Sn, n > 1), derived from hydrogen sulfide (H2S), have been considered to be involved in cytoprotective processes and redox signaling. The emerging evidences imply that the actual signaling molecule is H2Sn rather than H2S. In this work, we present a near-infrared fluorescent probe BD-ss for the selective detection of H2Sn biosynthetic pathways in living cells and in viv...
متن کاملA highly selective turn-on near-infrared fluorescent probe for hydrogen sulfide detection and imaging in living cells.
We have described a turn-on near-infrared fluorescent probe Cy-NO(2) based on nitro group reduction for intracellular H(2)S detection. The probe employs cyanine dye as a fluorophore, and is equipped with a nitro group as a fluorescent modulator. It is readily employed for assessing intracellular H(2)S level changes, and confocal imaging is achieved successfully.
متن کاملHydrogen sensing by localized surface plasmon resonance in colloidal solutions of Au-WO3-Pd
Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...

A new polymerizable fluorescent sensor based on the photoinduced electron transfer PET for the selective determination of fluoride ions in DMF solutions has been synthesized. The sensing system was prepared by incorporating 4-Amino-1,8-naphthalimide derivatives containing thiourea side chain at the amino moiety AFTN as a neutral F- selective flourophore and was characterized by use of the DSC, ...
