Recent strides in micro‐ and nanofabrication technologies have enabled researchers to design and develop micro‐ and nanoscale robotic systems with enhanced power, functionality, and versatility. Because of their capability of remote actuation and navigation, synthetic micro‐ and nanomotors powered by oscillating magnetic fields have recently gained considerable attention. In this article, a new type...
In article number 1706066, Guangyu Zhang, Longqiu Li, Wei Wang, and co‐workers report a magnetic surface walker that is precisely manipulated via an oscillating magnetic field. Magnetically coated Janus microspheres align and bind into dimers and leap into directional motion by alternating their two spheres back and forth in an asymmetric fashion dictated by the underlying substrate. They can circumvent...
