Directed nanoparticle self‐organization and twophoton polymerization are combined to enable three‐dimensional soft‐magnetic actuators with complex shapes and shape‐independent magnetic properties as demonstrated by the twisttype microactuators. As discussed by C. Peters and co‐workers on page 5269, generic and facile combination of glycine grafting and subsequent protein immobilization exploits the actuator's increased surface area, providing for a swimming microrobotic platform with enhanced load capacity desirable for future biomedical applications.
