Optoacoustic‐Guided Magnetic Microrobot Platform for Precision Drug Delivery
Abstract
Precision drug delivery remains a significant challenge due to limitations in drug loading, targeted release, precise navigation, and real‐time monitoring. Here, the study reports a magnetic microrobot platform (MMP) that integrates high‐capacity drug loading, magnetically actuated collective navigation, controlled drug release, and real‐time 3D optoacoustic imaging in a single system. The MMP exploits synergistic advantages by embedding hard‐magnetic FePt nanoparticles in a degradable ZIF‐8 shell, achieving a drug loading efficiency of ≈93.9% and enabling precise release in response to pH changes and radiofrequency‐induced heating. Reconfigurable swarm behavior strategies significantly enhance the navigation efficiency of microrobots against physiological blood flows within complex cerebral vasculature. The ex vivo and in vivo experiments further demonstrate strong contrast characteristics of the microrobots, enabling high‐resolution visualization of deep vascular structures and dynamic tracking of MMP with real‐time 3D optoacoustic imaging. This multifunctional strategy paves the way for clinical translation and precision therapy in complex biological settings.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
