Twirling DNA Rings - Swimming Nanomotors Ready for a Kickstart
Igor M. Kulic, Rochish Thaokar, Helmut Schiessel
Abstract
We propose a rotary DNA nanomachine that shows a continuous rotation with a frequency of 102 -104 Hz. 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 microns per second.
