DNA robots sort as they walk

Multiple DNA robots perform parallel tasks on a self-assembled DNA origami surface 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.
