Shape-Changing Soft Robots

Biochemical engineers at Johns Hopkins University have used sequences of DNA molecules to induce shape changing in water- based gels, demonstrating a new tactic to produce soft robots and “smart” medical devices that do not rely on cumbersome wires, batteries, or tethers.

Molecular Bridge Building

In a microscopic feat that resembled a high-wire circus act, a Whiting School team has coaxed DNA nanotubes to assemble themselves into bridgelike structures arched between two molecular landmarks on the surface of a lab dish.
