Cluster Alumnus Kevin Jahnke is second author and Cluster PI Prof. Dr. Kerstin Göpfrich is co-author of a pioneering paper published in Nature Communications. The research team succeeded for the first time in developing a ring of DNA nanotubes that could be used for artificial cell division. The results have provided new insights into the formation of DNA nanotube rings and the architecture of their contraction mechanism. Findings based on DNA-based contractile rings could be used to create artificial machines for dividing or contracting muscle-like materials.
