New Molecular Robot Can Be Programmed to Follow Instructions

Scientists have developed a programmable “molecular robot” — a sub-microscopic molecular machine made of synthetic DNA that moves between track locations separated by 6nm. The robot, a short strand of DNA, follows instructions programmed into a set of fuel molecules determining its destination, for example, to turn left or right at a junction in the track. The report, which represents a step toward futuristic nanomachines and nanofactories, appears in ACS’s Nano Letters.
