A glass that builds and heals itself

That looks a whole lot like solgels to me, but I'll admit that my knowledge of solgel chemistry is about twenty five years out of date and based on a single summer of research at Miami University (no, not University of Miami).

The video summarizes researchers' findings that amino acids can form glasses with an index of refraction close to that of silica glass, adhesive properties, and a natural inclination to form convex lens shapes...and that self heal themselves as they rehydrate themselves.
