LLPS droplet size estimation via UV-Vis spectroscopy using a microplate reader.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Liquid-liquid phase separation (LLPS) is critical to the formation of membraneless organelles within cells. Monitoring the size and dynamics of LLPS droplets is essential to understanding their function. However, conventional methods, such as microscopy and dynamic light scattering (DLS), have limitations, including low throughput and complex setups. Here, we present a simple, label-free, high-throughput method for estimating droplet size using ultraviolet-visible (UV-Vis) spectra obtained using a standard microplate reader. This method is theoretically supported by Mie scattering theory. By analyzing the spectral shape and comparing it to that of glass beads of known sizes, our method enables the quantitative estimation of LLPS droplet size in a minimally invasive manner. We validated our approach using peptide droplets of known sizes, then applied it to monitor the growth of protein condensates formed by vesicle-associated membrane protein-associated protein B (VAPB). This technique offers a convenient, scalable alternative for screening LLPS dynamics in various biomolecular systems.
