Brownian Dynamics Simulation of Microscale Thermophoresis in Liquid.
Article in ACS omega, 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
Microscale thermophoresis (MST) has garnered significant attention as a manipulation method for chemical species ranging from nanometers to micrometers in liquids. In particular, techniques for manipulating single nanometer-sized objects have been developed by driving MST through laser heating with near-infrared wavelengths focused down to submicron scales or via photothermal conversion of plasmonic nanoparticles. While MST simulations on a macroscopic scale can be addressed by solving the diffusion equation using the finite element method, alternative computational approaches are required to investigate thermophoretic behavior at the single-particle level. For this purpose, we have developed a numerical method for the thermophoresis of individual nanoparticles diffusing in a liquid by combining the finite element method for steady-state heat conduction with Brownian dynamics simulations. The scripts for the finite element method and Brownian dynamics calculations used in the present simulations are uploaded in the Supporting Information and freely available. The numerical results demonstrated satisfactory agreement with the experimental results of laser-induced thermophoresis performed on polystyrene nanoparticles with a diameter of 500 nm in water. This computational method is highly useful for controlling MST at the single-particle level, enabling the design of spatial temperature distributions and the evaluation of thermophoretic forces acting on individual nanoparticles.
