Surgical procedures almost always require some form of sutures or stitches to seal any incisions that were made during the procedure. However, stitches often burst or can loose and they are itchy and uncomfortable for patients. Now, researchers from the University of Maryland have found a way to more securely seal surgical incisions that may supplement or even eliminate the need for sutures.
The solution comes in the form of polymer nanofibers which can be sprayed directly onto the skin using a hardware-store-grade airbrush. In lab tests, the polymer sealed wounds and kept them protected for 42 days before degrading naturally. The developers see potential for this technology in various aspects of medicine as it serves not only to seal wounds but also can adhere to tissue.
