Fluorescence quenching by photoinduced electron transfer: a reporter for conformational dynamics of macromolecules. Photoinduced electron transfer (PET) between organic fluorophores and suitable electron donating moieties, for example, the amino acid tryptophan or the nucleobase guanine, can quench fluorescence upon van der Waals contact and thus Under acidic conditions, a fluorescence-quenching process of 1 induced by selective binding of alkali metal ions was discovered. The mechanism of this new process involves alkali metal ion-induced deprotonation of the ammonium ion to trigger resumption of a fluorescence-quenching PET process. PET‐quenching has been used as reporter for monitoring conformational dynamics in polypeptides, proteins, and oligonucleotides.

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 quenching, Fluorescence anisotropy, Fluorescence resonance energy transfer (FRET) Biophysics seminar Dept.

Efficient fluorescence quenching via photoinduced electron transfer (PET) requires van der Waals contact and can be used as reporter for structural fluctuations at the 1-nm scale in proteins, peptides, and nucleic acids.

A variety of molecular interactions can result in quenching. These include excited-state reactions, molecular rearrangements, energy transfer, ground-state complex formation, and colli-sional quenching. Fluorescence quenching of a molecule by a quencher can be due to processes such as ground state complex formation, excited state reactions, energy transfer, collisional quenching etc.

The following acridinedione dyes were selected for anion sensing. Fluorescence quenching refers to any process that decreases the fluorescence intensity of a sample. A variety of molecular interactions can result in quenching. These include excited-state reactions, molecular rearrangements, energy transfer, ground-state complex formation, and colli-sional quenching.

Excited-state dynamics studies, TD-DFT calculations, X-ray and NMR support the existence of a folded conformation for the 2-(dimethylamino)ethyl chain upon the imide ring in apolar solvents, where the dimethylamino group would quench the fluorescence by a PET effect, while in polar solvents the chain has an extended conformation, where the PET is hindered. Photoinduced electron transfer (PET) is an excited state electron transfer process by which an excited electron is transferred from donor to acceptor.

The experiments were repeated five times, and the phenomenon was consistent. The fluorescence of Q‐annexin V is quenched (OFF) by photoinduced electron transfer (PET) interactions between the conjugated NIR fluorophore and amino acid quenchers (tryptophan and/or tyrosine) in close proximity (0.5–1.5 nm).
