On mechanisms of fluorescence quenching by water

Biophysics, 2014
Mechanisms of fluorescence quenching of aromatic chromophores by water are reviewed. The mechanisms include polarity of chromophore environment, proton or electron transfer between the excited chromophore and water. A hypothesis is proposed that the quenching can be a result of chromophore-solvent hydrogen bond breaking in the excited state.

Fluorescence quenching studies with proteins

Analytical Biochemistry, 1981
Abstract 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 ...

Fluorescence quenching of tryptophan by trifluoroacetamide

Biochimica et Biophysica Acta (BBA) - General Subjects, 1984
Trifluoroacetamide 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.

Increasing Photothermal Efficacy by Simultaneous Intra‐ and Intermolecular Fluorescence Quenching

Advanced Functional Materials, 2019
Recently, 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 ...

Magnetic quenching of fluorescence

Chemical Physics Letters, 1977
Abstract 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.
