| Abstract: | Efficient propulsion and effective direction control are essential for self‐propelled micro/nanomotors. Here, a new “two‐in‐one” strategy for making attractive light‐driven micro/nanomotors is demonstrated. We make use of the metallic and magnetic properties of low‐cost Ni and incorporate just a single Ni layer into ZnO‐based microrockets, so that the resulting ZnO‐Ni microrockets can be both efficiently propelled by low energy (low light intensities and fuel concentrations) and effectively steered by a magnetic field. This successful demonstration of ZnO‐Ni microrockets is significant for the development of highly efficient synthetic micro/nanomotors, which have strong delivery ability and efficient direction control for future applications across the micro/nanoscale field. |
