Abstract

In vivo imaging and actuation of a swarm of magnetic helical microswimmers by external magnetic fields (less than 10 mT) in deep tissue is demonstrated for the first time. This constitutes a major milestone in the field, yielding a generation of micrometer-scale transporters with numerous applications in biomedicine including synthetic biology, assisted fertilization, and drug/gene delivery.
