A simple and general fabrication method for magnetic helical micromachines with or without claw‐like protrusions is reported by Li Zhang and co‐workers on page 811 . The dynamics of motion control reveal that corkscrew motion can always be generated when the input frequency of the rotating magnetic field is sufficiently high. The micromachines exhibit excellent swimming behavior, low cytotoxicity, and are capable of 3D cargo transport in fluid.
