Fluorescence quenching studies with proteins
Analytical Biochemistry, 1981Abstract A review is presented on the use of the technique of solute fluorescence quenching to study the structure and dynamics of proteins. A number of factors are discussed that must be considered in analyzing such data. Among these factors are the efficiency of the quenching process, the relative importance of static quenching, the heterogeneity ...

Increasing Photothermal Efficacy by Simultaneous Intra‐ and Intermolecular Fluorescence Quenching
Advanced Functional Materials, 2019Recently, using in situ self‐assembly‐induced fluorescence quenching (i.e., intermolecular quenching denoted herein) of a photothermal agent (PTA) to enhance its photothermal efficiency has proven to be a successful photothermal therapy (PTT) strategy ...

Fluorescence quenching of tryptophan by trifluoroacetamide
Biochimica et Biophysica Acta (BBA) - General Subjects, 1984Trifluoroacetamide was found to be a good quencher of tryptophan fluorescence, and the quenching was shown to proceed via both a dynamic and a static process. The respective quenching constants were determined by the measurement of the decrease of the fluorescence lifetime in the presence of the quencher.

Two-dimensional layered transition-metal dichalcogenide nanosheets have shown great potential in biosensors owing to their unique properties. Here, we exfoliated ultrathin metallic and semiconductive MoS2 nanosheets based on a chemical exfoliation method.

Magnetic quenching of fluorescence
Chemical Physics Letters, 1977Abstract The direct and indirect mechanisms for the magnetic enhancement of radiationless decay processes are described, and used to account for the experimental observations of the magnetic quenching of fluorescence from carbon disulphide, glyoxal, and nitrogen dioxide.

Langmuir, 2018
The fluorescence quenching property of graphene oxide (GO) has been newly demonstrated and applied for fluorescence imaging and biosensing. In this work, a new nanostructure was designed for effectively studying the quenching ability of GO.

The adsorption of methyl red (MR) isomers (ortho, meta, and para) on metal-organic frameworks (MOFs) was investigated by using a fluorescence quenching technique. All three MR isomers were found to quench the fluorescence of MOFs effectively.

Detection of oxygen by fluorescence quenching
Applied Optics, 1985The incorporation of an aromatic hydrocarbon fluorescent compound into silicone allows utilization of fluorescence quenching as a mechanism to measure molecular oxygen concentration in the composite matrix. Excitation and emission spectra of the aromatics change in agreement with the Franck-Condon model when the universal solvent is benzene ...
