Optical control of single-atom dynamics in plasmonic nanogaps.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Observing and controlling dynamics of single atoms in ambient conditions is challenging when using conventional atomic-scale techniques due to their invasive character. Here, such control is achieved optically, by confining pulses of visible light within extreme plasmonic nanogaps, where they rapidly create ("write") an adatom on one facet surface. Such adatoms are shown to be storable in ambient conditions for at least a week in the dark and are observed ("read") using low-intensity surface-enhanced Raman spectroscopy (SERS). Writing at higher optical intensities stabilizes the atomic protrusion through light-induced local restructuring, which imposes a higher energy barrier for its return into the metal surface. Fluctuations in these "picocavity" SERS spectra show that while adatom movement is significantly slower under low light intensities, ambient thermal energy still enables them to explore the surrounding energetic landscape. Optical control over single metal atom dynamics opens promising avenues for next-generation microelectronics, atomic-scale imaging, and catalysis.
