Researchers have just developed a new type of sealant that meets all the requirements of an effective surgical tool: Northeastern University says that their hydrogel, MeTro, is ideal, being that it is elastic, adhesive, non-toxic, and biocompatible. It's created with proteins similar to those that make up elastin in humans and sets in just 60 seconds with the help of a UV light.
MeTro was tested in rats by using it to seal incisions in arteries and punctures in lungs. It was also able to successfully seal wounds in pig lungs even during repeated inflations and deflations. The next step is to test the sealant in people. "The potential applications are powerful, from treating serious internal wounds at emergency sites such as following car accidents and in war zones, as well as improving hospital surgeries," said Anthony Weiss, a researcher at the University of Sydney and an author of the study.
