Without a scratch: Self-healing materials

This episode explores materials that mimic the human skin's ability to heal scratches and cuts. For a first-hand look at self-healing plastics, we visited the lab of Nancy Sottos, Ph.D., professor of engineering at the University of Illinois at Urbana-Champaign. Inspired by human skin, the plastics repair themselves by "bleeding" healing agents when they are cut or scratched. This research offers the promise of cell phones, laptops, cars, and other products with self-repairing, longer-lasting surfaces.
