title: Putting a brake on an autonomous DNA nanomotor.
abstract: A strategy was developed to reversibly switch on/off an autonomous DNA nanomotor that contains a DNA enzyme. The multiple RNA cleavage of the DNAzyme powered the motor to move, and a strand displacement mechanism provided the basis for a reversible brake to the motor.
