Fig. 1(A) Schematic diagram of the molecular robot. Molecular actuators work inside the robot, and the shape of the artificial cell membrane, which are bodies, are changed. When a DNA signal is input, the "molecular clutch," which transmits the force from the actuator, controls the shape-changing behavior. (B) Microscopy images of molecular robots. When the input DNA signal was "stop," the clutch was turned "OFF," and consequently, the shape-changing behavior was terminated (left side). The initiation of the shape-changing behavior when the DNA signal input was "start" was also confirmed (right side). Scale bar: 20 μm. The white arrow indicates the molecular actuator part that transforms the membrane.
