Surgery can be risky business, especially when it comes to getting sealed back up. Stitches, staples, and sutures are all foreign materials that have problems of their own. MeTro is a new type of surgical glue that is safe for the body, strong, and elastic. MeTro can seal wounds in sixty seconds and is made of an elastic protein that stretches with the skin or organ and is absorbed by the body during healing.
MeTro is injected into the wound and then ultraviolet light is used to activate the compound and secure it to the skin or tissue. Scientists and engineers from The University of Sydney and universities in The United States have been working on the glue.
The beauty of the MeTro formulation is that, as soon as it comes in contact with tissue surfaces, it solidifies into a gel-like phase without running away. We then further stabilize it by curing it on-site with a short light-mediated crosslinking treatment. This allows the sealant to be very accurately placed and to tightly bond and interlock with structures on the tissue surface. ~Nasim Annabi (Northeastern University Boston)
When you watch MeTro, you can see it act like a liquid, filling the gaps and conforming to the shape of the wound. 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. ~Anthony Weiss (University of Sydney)
This new glue seems to be a much better solution than traditional ways of sealing and caring for topical and internal wounds. It will be interesting to see how long it takes for this to be the norm in all hospitals and healthcare fields.
