Autonomous Bipedal Robot Built Out Of DNA
By Evan Ackerman
I don’t know enough about molecular biology for how this works to make any sense to me, but apparently, researchers at NYU have created an autonomous bipedal walking robot out of a single strand of DNA with a linkage in the middle. I’m going to just let them explain how it works:
The walking device consists of a strand of DNA that contains a 5’,5’ linkage in the middle. One leg is called L-E and the other is called L-O. It walks on a track consisting of a series of stem-loops (T1-T4) that are part of a stiff DX motif. It is fueled by a pair of successive stem-loops (F1 and F2) that are in solution. The driving force for its motion is the formation of more base pairs than exist at any given time. The system is shown below…
