In recent years, micro/nanomotors have become an important research field in nanotechnology. Light-driven micro/nanomotors have received extensive attention due to the advantages of high controllability, good programmability, and easy operation, as well as their potential in environmental remediation and biomedical applications. Herein, Chapter 1 introduces the background and motion mechanism of the field of light-driven micro/nanomotors, the design principles of light-driven micro/nanomotor materials, and the motion modes of individual motors and group motors. In addition, the current development and applications in this field are also discussed. The second chapter of the dissertation will focus on the work of applying single-atom catalysis to enhance the performance of nanomotors and the related application. The third chapter of the dissertation will discuss the work of developing light-driven SrTiO3:Al-based nanomotors for antimicrobial applications. The last chapter of the dissertation will summarize the conclusion of this dissertation and serve as a paradigm to rationally design novel light-driven nano/micromotors based on cutting-edge photocatalysts with outstanding catalytic performance for potential environmental and biomedical applications.
