LIT UPDATE - Gecko and frog toes' inspired nano adhesives
Summer's here and that means insects are out and about, including geckos and frogs. Even though they can be annoying, they are marvelous creatures that can defy gravity by sticking on walls, sometimes even holding themselves upside down just by using their toes! Can we make something that can help us defy gravity, and potentially make Spiderman a reality? Learn all about how scientists from The Institute of Technological Science in Wuhan University make nano adhesives inspired by geckos' and frogs' toes!
