Engineers create spiderweb-inspired tape that could replace surgical sutures

Inspired by the sticky substance spiders use to catch their prey, Massachusetts Institute of Technology engineers have designed a special double-sided tape that can rapidly seal tissues together, according to researchers. The new discovery has only been tested on rat and pig tissue — including the small intestine, stomach, liver and skin — but scientists hope it will eventually replace sutures, which they say don’t always work and may cause infections. They found that the new tape can bind tissues within just five seconds, according to MIT News. “There are over 230 million major surgeries all around the world per year and many of them require sutures to close the wound, which can actually cause stress on the tissues and can c ...
