Acoustically powered micro-clampbot for single-particle transportation.
Article in Science advances, 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
Acoustic microrobots offer an easy-to-operate approach for microobject manipulation in biomedical and nanotechnology applications. However, microobject transportation tasks require synergistic handling and movement, which poses a challenge for solely acoustically powered microrobots. These systems often require additional actuation mechanisms, such as magnetic control, for assistance. To address this challenge, we developed an acoustically powered micro-clampbot capable of clamping objects using claws actuated by acoustically induced secondary Bjerknes forces and moving via flagella that oscillate under acoustic input. The robot's actions are governed by distinct acoustic frequencies, enabling precise and independent control of clamping and locomotion. The micro-clampbot can pick a single particle from a cluster and navigate delicately through narrow channels, with narrow necks (~2.1 times the width of the micro-clampbot). This system facilitates the targeted transportation of microscale objects, including live cells, without causing damage. This versatile design highlights the potential of solely acoustically powered microrobots for advanced clinical therapies and microscale operations.
