Geckos are doing more than just promoting car insurance these days. According to a study published in the current issue of The Proceedings of the National Academy of Sciences, they are also the inspiration behind a new waterproof bandage.
Researchers at MIT and Harvard have been creating a bandage that replicates the tiny hills and valleys on the geckos' paws, allowing that adhesive to grip and interlock with tissues. They also added a sugar-based glue to the bandage that allows it to stick to wet surfaces. And finally, the bandages are biodegradable so you never have to peel them off.
Studies on pig intestines show the gecko bandages were twice as strong as others that did not have the lizard pattern. The hope is that these bandages could be used in operating rooms during surgery to repair wounds.
