The time it takes to control DNA-based molecular machines speeds up from several minutes to less than a second, thanks to a new, magnetic control system. Researchers shrank the functionality of magnetic particles used in previous studies by a thousand-fold -- from micro-scale to nano-scale -- to command the machines, and incorporated fluorescent beacons to monitor them.
