In recent years, there has been a growing interest in engineering dynamic and autonomous systems with robotic functionalities using biomolecules. Specifically, the ability of molecular motors to convert chemical energy to mechanical forces and the programmability of DNA are regarded as promising components for these systems. However, current systems rely on the manual addition of external stimuli, limiting the potential for autonomous molecular systems.

- A new Vernier mechanism for DNA origami nanostructures is introduced, allowing control over their size through a mechanical design involving a hollow cylinder and a rotatable shaft.
- The mechanism enables stacking of the DNA structures based on shape complementarity, with the number of stacked units regulated by the twisting angle of the shaft.
- Experimental results indicate that varying the twisting angle leads to different average lengths of the DNA assemblies, demonstrating how design adjustments can influence polymerization.
