“The geckos stuck just as well under water as they did on a dry surface, as long as the surface was hydrophobic [water-loving],” Stark explains. “We believe this is how geckos stick to wet leaves and tree trunks in their natural environment.”
The study has implications for the design of a synthetic gecko-inspired adhesive. Geckos' ability to stick to trees and leaves during rainforest downpours has fascinated scientists for decades, leading a group of University of Akron researchers to solve the mystery.
