DNA nanotechnology enables the precise fabrication of DNA-based machines with nanoscale dimensions. A wide range of DNA nanomachines are designed, which can be activated by specific inputs to perform various movement and functions. The excellent rigidity and unprecedented addressability of DNA origami have made it an excellent platform for manipulating and investigating the motion behaviors of DNA machines at single-molecule level. In this Concept, power supply, machine actuation, and motion behavior of DNA machines on origami platforms are summarized and classified. The strategies utilized for programming motion behavior of DNA machines on DNA origami are also discussed with representative examples. The challenges and outlook for future development of manipulating DNA nanomachines at the single molecule level are presented and discussed.
