Many clams glue themselves onto a solid surface like a rock or coral reef to keep from being tossed about by the surf. The “glue” sets when wet and is extremely strong, partly because tiny fibers enable the glue to self-heal. Similarly, scientists have discovered that a form of bacteria produces an amazingly water-repellent substance called biofilm that “greatly surpass[es] the repellency of Teflon.”1

If man-made materials similar to this clam adhesive and biofilm could be produced, they would have wide-ranging applications. And that’s exactly what some scientists have been attempting.

Researchers investigated the super-strong glue bond of mussels, a type of clam that inhabits turbulent intertidal zones. They found that the glue works so well because it has structures at the molecular level that form bonds with iron atoms. Unlike covalent bonds, which require specified chemistry for them to reform after they’re broken, these bonds between metal and molecule spontaneously reform after they break. This way, the mussels’ glue resets between one crashing wave and the next, keeping them securely in place.
