We propose a rotary DNA nanomachine that shows a continuous rotation with a frequency of around 100. This motor consists of a DNA ring whose elastic features are tuned such that it can be externally driven via a periodic temperature change. As a result, the ring propels itself through the fluid with a speed up to tens of nanometers per second.
