51_10c/2012Inside Back Cover: An Autonomous and Controllable Light-Driven DNA Walking Device (Angew. Chem. Int. Ed. 10/2012)

A nanorobot is able to perform autonomous locomotion and control the initiation, termination, and velocity by light. In their Communication on page 2457 ff., X. Zhang, W. Tan, and co-workers report the design of a DNA walking device by incorporating photosensitive moieties within DNA enzyme analogue structures. Based on the phenomenon of pyrene-assisted photolysis of disulfide bonds, this nanorobot shows the operational freedom and mechanical speed reminiscent of protein motors.
