Locomotion trajectory control of protein motors (l = 1 mm) via active magnetic steering. a Magnetic motors (SPION and protein nanocomposite) are self-propelled by the protein motor and steered by a magnetic field. Complex 2D motion trajectories: (b) triangle, (c) square, (d) pentagram, and (e) lemniscate trajectories were programmed and defined by a variable magnetic field \({\vec{\mathbf{B}}}\). Arrows show the direction of the magnetic field \({\vec{\mathbf{B}}}\)
