In 2007, researchers from the [[University of Akron]] and [[Rensselaer Polytechnic Institute]] announced they had developed a form of flexible, reusable [[gecko tape]] using [[carbon nanotube]]s to create microscopic [[synthetic setae]] and [[spatula]]e capable of

In 2008 researchers from the [[University of Dayton]] reported a gecko glue capable of supporting 100N/cm<sup>2</sup>, ten times the strength generated by a gecko's foot. The research also used carbon nanotubes, but included a curled end which allowed stronger binding but easy removal.<ref>{{Cite journal
