Self-healing Hydrogels

Researchers at the University of California, San Diego have engineered a hydrogel that has self-healing properties. The hydrogels have velcro-like capabilities and are able to bind to other pieces of the same type of hydrogel using “dangling side chains” or “arms” to grab and hold on to each other. This self-healing ability can be controlled by changing the pH of the solution the material is placed in. Researchers aim to further develop the hydrogels for possible use in drug delivery, healing stomach ulcers, and even as a sealant for acid leaks.
