Scientists have created a self-healing hydrogel, that responds to the acidity of its environment
Two pieces of the hydrogel, which bonded with one another when exposed to an acidic solution
Velcro is pretty handy stuff, but imagine if there was a soft, stretchy material with the same qualities. Well, now there is. Scientists from the University of California, San Diego have created a self-healing hydrogel that binds together in seconds, essentially copying the Velcro process at a molecular level. The new material could potentially find use in medical sutures, targeted drug delivery, industrial sealants and self-healing plastics.
