• ); time-dependent AFM; Introduction Light has been recognized as a versatile external energy source to actuate micro/nanorobots with outstanding merits of wireless, remote, and precise controllability [1][2][3][4]. Light-driven micro/nanorobots convert light into mechanical motion and are able to perform

• biomedical fields, such as medical diagnosis, nanoscale surgery, and targeted therapy. In this article, recent progress on micro/nanorobots is reviewed regarding actuation technologies. First, the different actuation mechanisms are divided into two types, external field actuation and self-actuation. Then, a

• few latest achievements on actuation methods are presented. On this basis, the principles of various actuation methods and their limitations are also analyzed. Finally, some key challenges in the development of micro/nanorobots are summarized and the next development direction of the field is explored
