DNA Triggers Shape-Shifting in Hydrogels, Opening a New Way to Make ‘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. The research advance, supervised by three faculty members in the university’s Whiting School of Engineering,
