DNA nanobots can exponentially self-replicate
DNA can be used to make nanomachines Kiyoshi Takahase Segundo/Alamy Nanoscale “robots” made of DNA that rapidly self-replicate could be harnessed to manufacture drugs or other chemicals inside the body, say researchers. Feng Zhou at New York University and his colleagues created the tiny machines, which are just 100 nanometres across, using four strands of…
