Soft-magnetic microrobotics: nanomaterials, fabrications and biomedical applications

Abstract

Soft-magnetic microrobots are widely exploited in many applications and preferred over other propulsion mechanisms due to ease of implementation, long-range, low cost, dexterous, highly precise, biocompatible, and non-invasive. This chapter summarizes the transformative potential of soft-magnetic microrobots with a special focus on magnetic nanomaterials fabrication techniques, and their biomedical applications. With controlled navigation through intricate biological environments using external magnetic fields, these microrobots offer precise and targeted interventions. The chapter underscores the critical role of material selection for biocompatibility and effectiveness. By combining advanced fabrication methods with appropriate nanomaterials, soft-magnetic microrobots are poised to reshape healthcare practices, offering novel diagnostic tools, therapeutic options, and surgical advancements. This comprehensive overview offers insights into the evolving landscape of soft magnetic microrobots and their potential to revolutionize medical treatments.
