Teams at ETH Zurich reported a clinically‑oriented microrobotics platform that uses electromagnetic navigation to steer dissolvable, drug‑loaded microrobots through complex vasculature and cerebrospinal spaces in large animal models. The system integrates an electromagnetic Navion navigation array, a release catheter, and imaging to perform targeted heating and capsule dissolution for on‑site drug release. Results published in Science demonstrated controlled navigation in vitro and in vivo in sheep and porcine models, reaching small vessels and delivering payloads to thrombi‑like targets. Authors emphasized potential to reduce systemic side effects in stroke and other localized pathologies by concentrating therapeutics at disease sites. Translational hurdles remain — including scale‑up, biocompatibility, and regulatory pathways — but the work establishes a unified navigation‑delivery‑imaging framework that could enable new targeted therapeutic paradigms.
