Graphical Abstract

Thumbnail image of graphical abstract

Continuous rotation of DNA around its phosphate backbone is achieved with a simple nanomotor, which is driven by an electric field oscillated between four orientations (see image). The motor consists of a DNA rotor and a partially single-stranded DNA axle held between a surface and a magnetic bead. Rotation is caused by realignment of the rotor DNA with the oscillated electric field.
