Bioengineers develop smart, self-healing hydrogel

Bioengineers develop smart, self-healing hydrogel: "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."
