3D Printed Untethered Magnetic Bulb for Liquid Biopsy and Drug Delivery
Bibliographic record
Abstract
The untethered manipulation of miniature mag-netic mechanisms holds promise for applications in liquid biopsy and drug delivery within the human body. However, employing microrobots for precise liquid manipulation still remains an open challenge. In this study, a novel magnetic mechanism, “magnetic bulb”, which is a millimeter-scale structure resembling pipette rubber bulb, is fabricated using our lab-developed Digital Light Processing-based (DLP-based) 3D printing system. The magnetic bulb can be actuated by magnetic fields to perform various tasks such as sampling, transportation, and controlled release of target liquids. Served as a modular design, the magnetic bulb is assembled with robust external cage to develop an integrated bulb-cage capsule with enhanced sampling capability and resistance to external compression. The resulting capsule has demonstrated effective fluid sampling within a stomach model and drug delivery to biological tissues. Additionally, a magnetic swimmer is crafted by 3D-printing a helical tail onto the magnetic bulb, exhibiting improved locomotion capability and maneuverability by magnetic fields in aerial-aquatic scenarios.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
