Thermally assisted microbot transport through high-viscosity media.
Article in Scientific reports, 2025. 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
Many potential in vivo microbot (µbot) applications require transport through high-viscosity environments. We have previously demonstrated that rotating magnetic fields can be used to reversibly assemble and drive µbots composed of paramagnetic microparticles. In this, particle surface chemistry can be readily manipulated and the combination of chemical degradation and mechanical action used to enhance penetration of µbot swarms into gelled networks. Here we show that a thermal approach, created through a hyperthermia-induced heating of microparticles with complementary alternating magnetic fields, can also be used to enhance mechanical action by lowering local viscosity. In addition, we observe that a rapid µbot back and forth sweeping motion induced by the applied field significantly improves penetration rates by reducing both µbot size and viscous resistance.
