DNA nanoscience is the science and engineering of molecular-scale devices composed of DNA. In prior work, DNA devices have been engineered to do nontrivial serial computational and robotic tasks. On page 1112 of this issue, Thubagere et al. (1) report an experimental molecular robotic system that makes parallel use of multiple DNA robotic devices to execute a defined task. The results provide evidence that the powerful technique of parallelism, previously used in macro- and micro-robot systems, can be used for molecular robotics.
