From 2,3-Diazabicyclo[2.2.2]oct-2-ene to Fluorazophore-L, a membrane-bound fluorescent probe for antioxidants [PDF]

, 2004
The aim of this work was to synthesize and to establish a new fluorescent membrane probe for antioxidants by exploiting the exceptional properties of the long-lived fluorophore 2,3-diazabicyclo[2.2.2]oct-2-ene (DBO) alias Fluorazophore-P.

Thioamides as Fluorescence-Quenching Probes [PDF]

Biophysical Journal, 2013
Fluorescence-quenching probes can be used to study the dynamics, folding, and aggregation of appropriately labeled protein systems. Valuable structural information can be extracted from distance-dependent quenching experiments; however, the structural resolution is often limited by the large size of the chromophore labels typically required for this ...

Amine molecular cages as supramolecular fluorescent explosive sensors: a computational perspective [PDF]

, 2016
We investigate using a computational approach the physical and chemical processes underlying the application of organic (macro)molecules as fluorescence quenching sensors for explosives sensing. We concentrate on the use of amine molecular cages to sense

Fluorescence of Alexa fluor dye tracks protein folding. [PDF]

PLoS ONE, 2012
Fluorescence spectroscopy is an important tool for the characterization of protein folding. Often, a protein is labeled with appropriate fluorescent donor and acceptor probes and folding-induced changes in Förster Resonance Energy Transfer (FRET) are ...

Models and measurements of energy-dependent quenching. [PDF]

, 2013
Energy-dependent quenching (qE) in photosystem II (PSII) is a pH-dependent response that enables plants to regulate light harvesting in response to rapid fluctuations in light intensity.

Fullerenol Quantum Dots-Based Highly Sensitive Fluorescence Aptasensor for Patulin in Apple Juice

Toxins, 2022
A highly selective and sensitive aptasensor for detecting patulin (PAT) was constructed based on the fluorescence quenching of fullerenol quantum dots (FOQDs) towards carboxytetramethylrhodamine (TAMRA) through PET mechanism. The π-π stacking interaction
