Skin-inspired coating that's as hard as teeth and can heal itself

(American Chemical Society) Self-healing smart coatings could someday make scratches on cell phones a thing of the past. But researchers often have to compromise between strength and the ability to self-repair when developing these materials. Now, one group reports in ACS Nano the development of a smart coating that is as hard as tooth enamel on the outside but can heal itself like skin can.
