Abstract:

Targeted delivery in vivo has always been a difficulty that clinical medicine is eager to overcome. Magnetically controlled micro/nano robots are favored by researchers because of their advantages, such as remote control of movement, unbound contact, accurate targeting ability and insensitivity to biological substances. Its application range involves targeted drug delivery, precision surgery, cell operation, disease diagnosis and treatment, etc., which has great potential in a variety of biomedical applications. In recent years, some progress has been made in the research of magnetically controlled micro/nano robots. This review focuses on the magnetism, maneuverability, biomedical application, visual tracking and biosafety of magnetically controlled micro/nano robots.
