Slug-inspired, flexible medical bio-glue sticks to wet surfaces without toxicity. A super-strong ‘tough adhesive’ has been created that is non-toxic and binds to biological tissues with a strength comparable to the body’s own resilient cartilage, even when they’re wet. Inspired by the glue produced by a slug, the double-layered hydrogel material demonstrates both high adhesion strength and strain dissipation, making it useful in a variety of medical applications.
