Adhesive Surgical Hydrogel Seals Wounds without Sutures

Methacryloyl-substituted tropoelastin, or MeTro, is an elastic hydrogel compound that can be applied to internal or external wounds during surgery or in emergency situations. Once treated with UV light, MeTro’s sealant properties are activated within seconds, effectively staunching blood flow and quickly closing wounds. The hydrogel can even be fine-tuned to different degrees of elasticity depending on the intensity of UV light exposure.

In early phase research, MeTro was successfully tested on the arteries of rodents and lungs of pigs. Human clinical trials are expected to begin in 2018. The collaborating research teams from University of Sydney, Harvard University, and Northeastern University responsible for this compound are confident that MeTro will have a volume of uses beyond wound management.
