Magnetic field-mediated Janus particles with sustained driving capability for severe bleeding control in perforating and inflected wounds

Severe bleeding in perforating and inflected wounds with forky cavities or fine voids encountered during prehospital treatments and surgical procedures is a complex challenge. Therefore, we present a novel hemostatic strategy based on magnetic field-mediated guidance. The biphasic Janus magnetic particle ([email protected]2O3-T) comprised aggregates of α-Fe2O3 nanoparticles (Fe2O3 NPs) as the motion actuator, negatively modified microporous...
