Bandages Modeled After Gecko Feet

Monday, 13 Aug 2012 10:39 AM


Scientists have developed a new breed of what they say are better bandages modeled after an unusual source: Geckos' feet.
The development, reported by University of Akron researchers in the Journal of Experimental Biology, was based on scientists’ observations that the tiny hairs on geckos' toe pads enable them to cling, like Velcro, to vertical surfaces – even in wet conditions.
They are now refining a synthetic adhesive for bandages that builds on the reptiles' remarkable gripping power to allow them to stick when moist or on wet surfaces.

"We're gathering many clues about how geckos interact with wet surfaces and this gives us ideas of how to design adhesives that work under water," said Ali Dhinojwala, a UA scientist. "Nature gives us a certain set of rules that point us in the right direction. They help us understand limitations and how to manipulate materials."
According to the UA report, researchers noted that when a single water droplet is placed on the sole of a gecko toe, it repels the water. The anti-wetting property helps explain how they maneuver in rainy tropical conditions and is providing insight into the development of synthetic adhesives that grip in wet environments – such as inside the body, for surgical applications.
