Taking a cue from mussels’ sticky grip, researchers have developed a new adhesive material by decorating polymer backbones with catechol groups. Natural adhesives like those produced by mussels remain sticky when wet because of the binding ability of the catechol’s diol motif. A team led by Jang Wook Choi, Jung-Ki Park, and Haeshin Lee of the Korea Advanced Institute of Science & Technology designed the new adhesive binders to improve the . . .
