Controlled manipulation of Fe3O4 nanoparticles in an oscillating magnetic field for fast ablation of microchannel occlusion

Abstract

Fe₃O₄ nanoparticles were controlled by an oscillating magnetic field to enable fast and non-contact ablation of microchannel occlusion. Scalable behaviour of their translational and rotational velocities was experimentally verified. Rotational flows created by such motions are fundamental for ablation as demonstrated by the removal of thrombi in occluded microchannels.
