Surface-Sensitive Fractioning of Flowing Colloidal Suspensions Sedimented at a Photochemically Active Wall.
Article in Small (Weinheim an der Bergstrasse, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
A colloidal particle exposed to nonequilibrium inhomogeneities in the chemical-composition of the solution responds by phoresis with a magnitude dictated by its surface properties (adsorption of solutes relative to the solvent) and the strength of the inhomogeneity gradient. Fractioning by surface-properties for a suspension of sedimented colloidal particles flowing within a microfluidic device can then be achieved by exposing it to chemical-composition gradients normal to the wall. One such method is developed by employing a wall imbibed with a photo-sensitive surfactant; under suitable illumination, it undergoes reversible isomerization and turns the wall into a source of chemical inhomogeneities by isomers-exchange with the solution. Proof-of-concept experiments, complemented by theoretical modeling, demonstrate the feasibility of the proposed method in several examples of particles mixtures. The results highlight its potential in terms of high performance, simple technical requirements, and suitability for dealing with equally-sized-but surface different-particles.
