DNA screw, a rotary molecular motor
DNA-based molecular motor engineering is expected to achieve dynamically changing structures in the nanoscale world. Our project’s goal is realizing rotary motion in nanoscale. We designed the DNA-based structure called “DNA Screw.” This structure consists of a small cylinder inside a large ring, which are connected by DNA strands. The cylinder and ring are synthesized DNA origami. The DNA strands called DNA walkers proceed along a track set out spirally on the cylinder's outer-surface, and generate rotational movement.
