Researchers have developed a light-activated glue that can seal up heart blood vessels in seconds and hold tight under high pressure. The glue, called a hydrophobic light-activated adhesive (HLAA), could be used on the battlefield or in the emergency room during surgery to repair vascular defects and stop bleeding or hemorrhaging.
This animated video shows how the heart glue works, with an accompanying narration by author Jeffrey Karp.
