چکیده
A new fluorescent probe with a unique sequential dual FRET process was designed and constructed. This probe showed distinguished responses towards Fe(3+) and Hg(2+), making it an ideal candidate for multiple logic operations at the molecular level.

Reversible ratiometric detection of highly reactive hydropersulfides using a FRET-based dual emission fluorescent probe.
Hydropersulfide (R-SSH) is an important class of reactive sulfur species (RSS) involved in a variety of physiological processes in mammals. A fluorescent probe capable of real-time detection of hydropersulfide levels in living cells would be a versatile tool to elucidate its roles in cell signalling and redox homeostasis. In this paper, we report a ratiometric fluorescent probe for hydropersulf...
متن کاملA biotin-conjugated glutathione-responsive FRET-based fluorescent probe with a ferrocenyl BODIPY as the dark quencher.
An efficient ferrocenyl BODIPY based dark quencher has been developed and employed to construct a FRET-based fluorescent probe that contains a biotin moiety as a potential directing ligand for cancer cells and a glutathione-cleavable disulfide linker connecting the quencher and a distyryl BODIPY fluorophore. This molecular probe is deactivated in the native form through FRET followed by intramo...

متن کاملHairpin-like fluorescent probe for imaging of NF-κB transcription factor activity.
Three oligodeoxyribonucleotides (ODN) covalently labeled with near-infrared (NIR) fluorochromes were synthesized and characterized with a goal of comparing in vitro a hairpin-based and a duplex-based FRET probe designed for the detection of human recombinant NF-κB p50/p65 heterodimer binding to DNA. Using deoxyguanosine phosphoramidite with a phosphorus-linked aminoethylene (diethylene glycol) ...
متن کاملA FRET based pH probe with a broad working range applicable to referenced ratiometric dual wavelength and luminescence lifetime read out.
A luminescent probe for determination of pH was designed based on a Förster resonance energy transfer (FRET) system, combining a europium chelate as the donor and carboxynaphtho-fluorescein as a pH sensitive acceptor. The FRET system enables referenced pH detection in an exceptional broad dynamic range from pH 3 to 9.
