Hybrid phytoglycogen-dopamine nanoparticles as biodegradable underwater adhesives.

Summary: Imagine a super-glue that works perfectly underwater—like the sticky threads mussels use to cling to rocks—but is made from safe, natural ingredients found in sweet corn. Scientists have developed a new material called "PG-dopa" by combining tiny particles of phytoglycogen (a sugar) with dopamine (a sticky molecule). Unlike traditional medical glues that can be toxic or permanent, this new adhesive creates a strong bond in wet environments and then dissolves harmlessly into the body. This breakthrough could lead to safer, temporary implants and better ways to heal internal tissues.
