Stacking-induced fluorescence increase reveals allosteric interactions through DNA [PDF]

, 2018
From gene expression to nanotechnology, understanding and controlling DNA requires a detailed knowledge of its higher order structure and dynamics. Here we take advantage of the environment-sensitive photoisomerization of cyanine dyes to probe local and ...

Photobleaching Pathways in Single-Molecule FRET Experiments [PDF]

Journal of the American Chemical Society, 2007
To acquire accurate structural and dynamical information on complex biomolecular machines using single-molecule fluorescence resonance energy transfer (sm-FRET), a large flux of donor and acceptor photons is needed. To achieve such fluxes, one may use higher laser excitation intensity; however, this induces increased rates of photobleaching.

Hexameric helicase G40P unwinds DNA in single base pair steps

eLife, 2019
Most replicative helicases are hexameric, ring-shaped motor proteins that translocate on and unwind DNA. Despite extensive biochemical and structural investigations, how their translocation activity is utilized chemo-mechanically in DNA unwinding is ...

Don’t Be Fooled by Randomness: Valid p-Values for Single Molecule Microscopy

Frontiers in Bioinformatics, 2022
The human mind shows extraordinary capability at recognizing patterns, while at the same time tending to underestimate the natural scope of random processes. Taken together, this easily misleads researchers in judging whether the observed characteristics

Fluorescence energy transfer enhancement in aluminum nanoapertures

, 2015
Zero-mode waveguides (ZMWs) are confining light into attoliter volumes, enabling single molecule fluorescence experiments at physiological micromolar concentrations. Among the fluorescence spectroscopy techniques that can be enhanced by ZMWs, F\"{o}rster

Nanophotonic enhancement of the F\"orster resonance energy transfer rate on single DNA molecules

, 2014
Nanophotonics achieves accurate control over the luminescence properties of a single quantum emitter by tailoring the light-matter interaction at the nanoscale and modifying the local density of optical states (LDOS).

TFE and Spt4/5 open and close the RNA polymerase clamp during the transcription cycle [PDF]

, 2016
Transcription is an intrinsically dynamic process and requires the coordinated interplay of RNA polymerases (RNAPs) with nucleic acids and transcription factors.

Fast three-color single-molecule FRET using statistical inference

Nature Communications, 2020
Three-colour FRET is a powerful tool to study macromolecular conformational dynamics, but is temporally limited due to the experimental complexity.

Plasmonic antennas and zero mode waveguides to enhance single molecule fluorescence detection and fluorescence correlation spectroscopy towards physiological concentrations

, 2014
Single-molecule approaches to biology offer a powerful new vision to elucidate the mechanisms that underpin the functioning of living cells. However, conventional optical single molecule spectroscopy techniques such as F\"orster fluorescence resonance ...
