Controlled single-electron transfer enables time-resolved excited-state spectroscopy of individual molecules.
Article in Nature nanotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
An increasing number of scanning-probe-based spectroscopic techniques provides access to diverse electronic properties of single molecules. Typically, these experiments can only study a subset of all electronic transitions, which obscures the unambiguous assignment of measured quantities to specific quantum transitions. Here we develop a single-molecule spectroscopy that enables the access to many quantum transitions of different types, including radiative, non-radiative and redox, that is, charge-related, transitions. Our method relies on controlled alternating single-charge attachment and detachment. For read-out, the spin states are mapped to charge states, which we can detect by atomic force microscopy. We can determine the relative energies of ground and excited states of an individual molecule and can prepare the molecule in defined excited states. After a proof-of-principle demonstration of the technique on pentacene, we apply it to PTCDA, the scanning-probe luminescence of which has been interpreted controversially. The method may be used to guide, understand and engineer tip-induced chemical reactions as well as phosphorescence and fluorescence of individual molecules.
