Two-photon excitation two-dimensional fluorescence spectroscopy (2PE-2DFS) of the fluorescent nucleobase 6-MI

This paper introduces 2PE-2DFS to study DNA base conformations using 6-MI, revealing electronic-vibrational spectra and conformation-dependent exciton coupling in dimers.

Studies of DNA "breathing" by polarization-sweep single-molecule fluorescence microscopy of exciton-coupled (iCy3)2 dimer-labeled DNA fork constructs

This paper introduces a single-molecule fluorescence method to measure DNA breathing dynamics using (iCy3)2 dimer probes, revealing four conformational macrostates in DNA fork constructs.

Using transition density models to interpret experimental optical spectra of exciton-coupled cyanine (iCy3)2 dimer probes of local DNA conformations at or near functional protein binding sites

The paper uses transition density models to analyze optical spectra of (iCy3)2 dimer probes, determining DNA conformational parameters near protein binding sites.

Temperature-dependent local conformations and conformational distributions of cyanine dimer labeled single-stranded -- double-stranded DNA junctions by 2D fluorescence spectroscopy

This study uses 2D fluorescence spectroscopy to analyze temperature-dependent conformational changes in ss-dsDNA junctions labeled with cyanine dimer probes, revealing position-dependent structural disorder.

Sub-millisecond conformational transitions of short single-stranded DNA lattices by photon correlation single-molecule FRET

This paper uses smFRET to study sub-millisecond conformational transitions in short ssDNA lattices, revealing three macrostates with distinct end-to-end distances.

Dinucleotides as simple models of the base stacking-unstacking component of DNA 'breathing' mechanisms

The paper studies DNA breathing mechanisms at the dinucleotide level using simulations and experiments, identifying two chiral conformations and the role of ions and water.
