Programming Tactic Behaviors of Active Colloids via Surface Charge.
Article in ACS nano, 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
Self-diffusiophoretic colloids move autonomously by creating chemical gradients. These self-generated gradients lead to fluid motion at the particle surface, also known as phoretic slip, which determines the direction of colloidal motion. Phoretic slip is often modeled as dependent on the local chemical gradient and a material-dependent property called phoretic mobility. Reversing the direction of propulsion would require fine-tuning of these parameters. In this work, we show that by changing the charge of the colloids which has an effect on the phoretic mobility, we can indeed achieve a reversal in the direction of propulsion of Janus micromotors. In addition, we report that by simply tuning the surface charges of colloids, we can achieve reversals in much more complex tactic behaviors such as chemotaxis and rheotaxis. This work demonstrates a method for creating programmable active colloids by subtly tuning surface properties, contributing to the understanding of active matter.
