Fluorescence quenching between unbonded graphene quantum dots and gold nanoparticles upon simple mixing

, 2014
Fluorescence quenching is an interesting phenomenon that has been widely utilized in developing fluorescence-based sensors. However, most of the research focuses on the quencher and fluorophore in the bonded states. The fluorescence quenching between two

Modeling of fluorescence quenching by lutein in the plant light-harvesting complex LHCII.

Journal of Physical Chemistry B, 2013
Photoprotective non-photochemical quenching (NPQ) in higher plants is the result of the formation of energy quenching traps in the light-harvesting antenna of photosystem II (PSII).

QUENCHING OF METHYLCYCLOHEXANE FLUORESCENCE BY METHANOL*

Photochemistry and Photobiology, 1995
Abstract—We measured the fluorescence emission spectrum and intensity decays of methylcyclohexane (MCH) when excited by simultaneous absorption of two photons at 298 nm. The steady‐state intensities and lifetimes were both decreased by methanol, which was found to be an efficient quencher of MCH fluorescence.

Tunable star-shaped triphenylamine fluorophores for fluorescence quenching detection and identification of nitro-aromatic explosives.

Chemical Communications, 2013
Triphenylamine-based fluorophores containing pyrene or corannulene show variable fluorescence quenching sensitivity toward nitro explosives. The most sensitive fluorophore is capable of detecting TNT on the ng cm(-2) scale; the array is useful for ...

Fluorescence Quenching of Aminodiphenylamines with Chloromethanes

Collection of Czechoslovak Chemical Communications, 2002
The fluorescence quenching of 2-aminodiphenylamine (2ADPA), 4-aminodiphenylamine (4ADPA) and 4,4'-diaminodiphenylamine (DADPA) with tetrachloromethane, chloroform and dichloromethane have been studied in hexane, dioxane, acetonitrile and methanol as solvents.

Solute perturbation of protein fluorescence. The quenching of the tryptophyl fluorescence of model compounds and of lysozyme by iodide ion.

Biochemistry, 1971
The effect of iodide on the tryptophyl fluorescence of model compounds and of lysozyme was studied in order to evaluate the factors that determine the use of iodide as a selective quencher of the fluorescence of tryptophyl side chains of proteins exposed

Fluorescence Quenching Reactions

1991
The quenching of the fluorescence of biomacromolecules by solute quenchers has become a widely used and powerful technique (Lehrer, 1976; Lehrer and Leavis, 1989; Lakowicz, 1983; Eftink and Ghiron, 1981; Eftink, 1991). Such quenching reactions have been used primarily to obtain topographical information about proteins, nucleic acids, and membrane ...
