Thermosensitive Bioadhesives Enable Better Surgical Sealing

An injectable biomaterial with significantly improved adhesive strength, stretchability, and toughness could enable improved surgical sealing. This chemically modified, gelatin-based hydrogel has attractive features, including rapid gelation at room temperature and tunable levels of adhesion. This custom-engineered biomaterial is ideal as a surgical wound sealant, with its controllable adhesion and injectability and its superior adherence to a variety of tissue and organ surfaces.
