Fig. 36 shows six N-dansyl-amino acid-modified β-cyclodextrins (β-CDs) 108–110 prepared as enantioselective fluorescent sensors for alcohols and ketones in sodium phosphate buffer. In these compounds, a chiral amino acid spacer is used to link the CD ring with the dansyl fluorophore, which can improve the binding affinity Physikalisch-chemisches Praktikum I Fluorescence Quenching { 2016 Fluorescence Quenching Summary The emission of light from the excited state of a molecule (uorescence or phospho-rescence) can be quenched by interaction with another molecule.

Fluorescence quenching can be defined as a bimolecular process that reduces the fluorescence quantum yield without changing the fluorescence emission spectrum (Table 1); it can result from transient excited-state interactions (collisional quenching) or from formation of nonfluorescent ground-state species.

Fluorescence quenching mechanisms in micelles: the effect of high quencher concentration D.T. Cramb , S.C. Beck Department of Chemistry, University of Calgary, 2500 Fluorescence Quenching Mechanisms in Probes for Genetic Analysis Fluorescent probes are used in biochemical assays to monitor specific events such as binding, cleavage or conformational changes. Dual- labeled probes with a fluorophore and a quencher have many applications in genetic analysis such as amplicon detection in quantitative-PCR (qPCR). Fluorescence Resonance Energy Transfer is a method that allows the detection of a ‘distance-dependent’ interaction between the excited states of two distinct, dye-linked, molecules, i.e. the ‘fluorophore’ and the ‘quencher’. Quenched fluorescent peptides (‘FRET peptides’) are widely used as suitable substrates in enzyme studies.
