Each of these components is made of just a few nucleotides within a single strand of DNA.


In principle, these modular building blocks could be assembled in many different ways to complete different tasks.


For example, a DNA robot with several hands and arms Taurean Prince Hawks Jersey , could be used to carry multiple molecules simultaneously.


In the work described in the Science paper, the Qian group built a robot that could explore a molecular surface, pick up two different molecules and then distribute them to two distinct regions on the surface.


"The DNA robot moves around on a 58-nanometer-by-58-nanometer pegboard on which the pegs are made of single strands of DNA complementary to the robot's leg and foot," Qian's team said in a statement.


"The robot binds to a peg with its leg and one of its feet -- the other foot floats freely," the team said.


"When random molecular fluctuations cause this free foot to encounter a nearby peg, it pulls the robot to the new peg and its other foot is freed. This process continues with the robot moving in a random direction at each step."
