Fluorescence Resonance Energy Transfer Using Spiropyran and Diarylethene Photochromic Acceptors

open access: yesMolecules, 2000
We describe the preparation and photophysical characterization of two model compounds designed to test a new approach for the quantitative determination of Fluorescence Resonance Energy Transfer (FRET) in biological systems. The method enables modulation

Coherent cooperative fluorescence resonance energy transfer [PDF]

open access: yesOptics and Spectroscopy, 2014
Cooperative fluorescence resonance energy transfer effect is experimentally demonstrated for a few crystals doped with rare-earth ions. We show that, at the liquid helium temperatures in similar crystals, coherent cooperative fluorescence resonance energy transfer, as well as an inverse coherent up-conversion process, could be observed, and briefly ...

Highly-efficient quantitative fluorescence resonance energy transfer measurements based on deep learning

open access: yesJournal of Innovative Optical Health Sciences, 2020
Intensity-based quantitative fluorescence resonance energy transfer (FRET) is a technique to measure the distance of molecules in scale of a few nanometers which is far beyond optical diffraction limit.

Calculation on fluorescence resonance energy transfer on surfaces

open access: yesBiophysical Journal, 1980
A general method for estimating fluorescence resonance energy transfer between distributions of donors and acceptors on surfaces is presented. Continued fraction approximants are obtained from equivalent power series expansions of the change in quantum yield in terms of the fluorescent lifetimes or the steady-state fluorescence.

DNA Probes Using Fluorescence Resonance Energy Transfer (FRET): Designs and Applications

open access: yesBioTechniques, 2001
Fluorescence resonance energy transfer (FRET) is widely used in biomedical research as a reporter method. Oligonucleotides with a DNA backbone and one or several chromophore tags have found multiple applications as FRET probes.

Genotyping of IRGM tetranucleotide promoter oligorepeats by fluorescence resonance energy transfer

open access: yesBioTechniques, 2009
Fluorescence resonance energy transfer (FRET) genotyping has been well established for the rapid assessment of single nucleotide polymorphisms (SNPs) and deletions. A design is presented that allows the typing of short tandem oligo repeat sequences using

Advanced Data Analysis for Fluorescence-Lifetime Single-Molecule Localization Microscopy

open access: yesFrontiers in Bioinformatics, 2021
Fluorescence-lifetime single molecule localization microscopy (FL-SMLM) adds the lifetime dimension to the spatial super-resolution provided by SMLM. Independent of intensity and spectrum, this lifetime information can be used, for example, to quantify ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
