We report the design of a single-molecule nanomotor driven by photons. The nanomotor is a DNA hairpin-structured molecule incorporated with azobenzene moieties to facilitate reversible photocontrollable switching. Upon repeated UV–vis irradiation, this nanomotor displayed 40–50% open–close conversion efficiency. This type of nanomotor displays well-regulated responses and can be operated under mild conditions with no output of waste. In contrast to multiple-component DNA nanomachines, the intramolecular interaction in this single-molecule system offers unique concentration-independent motor functionality. Moreover, the hairpin structure of the motor backbone can significantly improve the efficiency of light-to-movement energy conversion. These results suggest that azobenzene-incorporated, hairpin-structured single-molecule DNA nanomotors have promising potential for applications which require highly efficient light-driven molecular motors.
