Multipair Förster Resonance Energy Transfer via Spectrally Resolved Single-Molecule Detection.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Förster resonance energy transfer (FRET) is a powerful tool for studying molecular interactions. Its use for studying interactions involving more than two molecules, however, has been limited by spectral crosstalk among the fluorophores. Here, we report multispectral FRET (msFRET) for imaging multiple pairs of interactions in parallel by spectrally resolving single fluorescent molecules. By using a dual (positional and spectral) channel and wide-field imaging configuration, fluorophores with emission maxima as close as 6-10 nm could be reliably distinguished. We demonstrate msFRET by continuously monitoring the hybridization dynamics among 2 × 2 pairs of DNA oligos in parallel using Cy3 and Cy3.5 as donors and Cy5 and Cy5.5 as acceptors. Aside from studying molecular interactions, msFRET may also find applications in probing fluorophore photophysics during FRET and in multiplexed superresolution imaging.
