Understanding shell coating effects to overcome quenching in single anisotropic upconversion nanoparticles.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Shell coating is known to suppress luminescence quenching in spherical upconversion nanoparticles. However, the emergence of anisotropic nanoparticles with facet-selective, directional growth complicates the coating process, and the use of traditional active, inert, or polymer coatings on such structures remains largely unexplored. Here, we synthesize a series of nanorods with designed geometries, enabling quantitative spectral analysis at the single-particle level. We observe that directional growth of inert or active shells at the rod tips enhances emission relative to the parent core, with their relative effectiveness governed by power density and shell thickness. Ligand presence-polymer or oleate-quenches upconversion relative to bare nanorods. Although local heating is observed at the single-particle level, it does not affect spectroscopic observations, ligand stability, or data reproducibility. Our findings reveal how directionally grown shells influence the optical properties of upconversion nanorods, providing essential insights for their future applications in bioimaging, sensing, and photonics.
