A surgical glue that it could replace staples and sutures used by doctors to seal up wounds. Because it is so fast-acting, it could be used at emergency sites, such as a car accident or a war zone, with the scientists likening its behavior once squirted into the wound to silicone sealants used around bathroom tiles. As soon as it comes in contact with tissue surfaces, it solidifies into a gel-like phase without running away.

The gel-like glue mixes natural, highly elastic proteins with light-sensitive molecules that enable it to set in 60 seconds when exposed to UV light. This UV-treatment cures the glue and allows it to form tight bonds with structures on the surface of the tissue, which maintains its elasticity. Also included is a degrading enzyme that can be manipulated to determine how long the glue lasts in the wound, ranging from hours to months, depending on the time it needs to heal.
