Injectable glue heals wounds in seconds

The injectable glue, MeTro, is based on a naturally occurring protein called tropaelastin. It is applied directly to the wound and is then activated with UV light to form a complete seal, eliminating the need for staples or stitches. Its elasticity means it’s designed to work well on shape-changing internal organs like the lungs and heart.

A study published in journal Science Translational Medicine showed the glue quickly and successfully sealed incisions in the arteries and lungs of rodents and the lungs of pigs.
