My Mussel Glue Can Beats Your Gorilla Glue
From the glands of its slug-like foot, a mussel secretes a glue that in less than five minutes - under water - hardens into a filament, or byssal thread, that will attach it for life to an intertidal rock. Mussel glue can resist forces of 1000 lbs/in2
. That's better than a barnacle. "There's no manmade glue that can do that underwater," says marine biologist Herbert Waite. Using Blue Mussels in his research, Waite is on the verge of creating the first synthetic mussel-like glue. It's all in the polymer cross-linking. Applications include surgery on hard and soft tissues, marine vessel repair, and dentistry. This is "disruptive technology" in the world of adhesives.
