A DNA-based nanorobotic arm driven by a molecular wind-up motor

Nature Physics volume 19, pages 626–627 (2023)Cite this article

Subjects

A DNA-based nanorobotic arm connected to a base plate through a flexible joint can be used to store and release mechanical energy. The joint acts as a torsion spring that is wound up by rotating the arm using external electric fields and is released using a high-frequency electrical pulse.
