Investigation of FRET from organic dyes to silver nanoparticles and structural properties using the DFT/TD-DFT approach

Chemical Physics Impact, 2022
The Forster resonance energy transfer involving a fluorescence molecule and organic quencher is constrained to a distance of ∼10 nm. However, with the coupling plasmonic materials, a significant amount of energy transfer can take place over substantially

Discrimination between FRET and non-FRET quenching in a photochromic CdSe quantum dot/dithienylethene dye system [PDF]

, 2014
A photochromic Förster resonance energy transfer (FRET) system was employed to disentangle the fluorescence quenching mechanisms in quantum dot/photochromic dye hybrids.

A STING-based biosensor affords broad cyclic dinucleotide detection within single living eukaryotic cells

Nature Communications, 2020
Cyclic dinucleotides are conserved second messengers but current detection methods are limited. Here the authors engineer a Förster resonance energy transfer (FRET) based biosensor, BioSTING, which gives real-time in vitro detection of these nucleotides.

Conformational and migrational dynamics of slipped-strand DNA three-way junctions containing trinucleotide repeats

Nature Communications, 2021
DNA three-way junctions are branched structures formed during replication, repair, and recombination, and are involved in models of repeat expansion. Here the authors use single-molecule Förster resonance energy transfer to reveal the dynamics of DNA ...

Temperature-tuning of near-infrared monodisperse quantum dot solids at 1.5 um for controllable Forster energy transfer [PDF]

, 2008
We present the first time-resolved cryogenic observations of Forster energy transfer in large, monodisperse lead sulphide quantum dots with ground state transitions near 1.5 um (0.83 eV), in environments from 160 K to room temperature.

T-cell Receptor Is a Threshold Detector: Sub- and Supra-Threshold Stochastic Resonance in TCR-MHC Clusters on the Cell Surface

Entropy, 2022
Stochastic resonance in clusters of major histocompatibility molecules is extended by a more detailed description of adaptive thresholding and by applying the notion of suprathreshold stochastic resonance as a stochastically quantizing encoder of ...

Excitation transfer in C-phycocyanin [PDF]

, 1988
Calculations of excitation transfer rates among the chromophores of C-phycocyanin using the Förster inductive resonance transfer mechanism have been carried out using the new coordinates for the position and orientation of the chromophores (Schirmer, T.,

Analysis of Enzyme Conformation Dynamics Using Single-Molecule Förster Resonance Energy Transfer (smFRET)

Biophysica, 2022
Single-molecule Förster resonance energy transfer (smFRET) enables the deconvolution of various conformational substates of biomolecules. Over the past two decades, it has been widely used to understand the conformational dynamics of enzymes.
