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.

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.
