Elementary Charge Characterization of Single Quantum Dots in Solution.
Article in Nano letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Measuring quantum dot properties at the single-particle level in their native liquid environment provides a powerful means of deepening our understanding of quantum dot systems and advancing their applications. In this work, we successfully measure the electrical charge of individual CdSe/CdS core/shell quantum dots, with diameters of 15 and 25 nm, in a nonpolar liquid, with precision at the elementary charge level. This is accomplished by combining laser scanning microscopy with high-field electrophoresis, where the observed electrophoretic mobilities show clear clustering around values corresponding to discrete charge states. A thermodynamic charging model captures the dominant features of the probability distribution and size dependence of the observed charges. This research opens the possibility to study charge-related optical and electronic phenomena at the single-quantum-dot level in solution.
