Analytical Ultracentrifugation in Different High-Density Media Allows to Assess Heterogeneity of mRNA-Lipid Nanoparticles.
Article in Small methods, 2026. 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
This study demonstrates the capability of analytical ultracentrifugation for assessing the morphological homogeneity of mRNA-lipid nanoparticles. Building on a standard method for density evaluation of nanoparticles, it demonstrates the importance of selecting the appropriate liquid medium for the experiments. Our research reveals the interaction between deuterated buffers and aqueous compartments of lipid-based particles. By investigating the sedimentation behavior of compact solid particles, liposomes, and lipid nanoparticles, we demonstrate that AUC can detect water-loaded cavities in mRNA-loaded lipid nanoparticles. Therefore, we suggest that performing sedimentation velocity experiments both in sucrose-containing buffer and deuterated solvents results in precious information not only on density but also on batch homogeneity and particle morphology.
