Rock and roll : The rotational and translational motion of magnetic Janus particles with nanoscopic surface structure can be controlled by an external magnetic field (see picture). The nanoscopic surface pattern enhances the microscopic motion of the microspheres by inducing strong coupling between rotation and translation. The separation of individual microspheres from the mixture in a microfluidic device is also demonstrated.
