摘要
Magnetic helical micro- and nanorobots can perfo rm 3D navigation in various liquids with a sub-micrometer precision under low-strength rotating magnetic fields(< 10 m T). Since magnetic fields with low strengths are harmless to cells and tissues, magnetic helical micro/nanorobots are promising tools for biomedical applications, such as minimally invasive surgery, cell manipulation and analysis, and targeted therapy. This review provides general information on magnetic helical micro/nanorobots, including their fabrication, motion control, and further functionalization for biomedical applications.
