Gecko-inspired adhesive tape could improve recovery from surgery
February 18, 2008
Researchers are close to developing a biodegradable surgical adhesive based on biomimicry of gecko feet. Geckos are famous for their ability to walk on ceilings and vertical surfaces.
The “gecko-inspired, nanopatterned” adhesive tape could supplement or replace sutures and staples in surgery.
Unlike previous gecko-inspired adhesive tape, the new material will work in wet conditions and could be doped with biochemicals to accelerate healing. The adhesive would dissolve after an injury heals.
The tape is currently being tested in rats for hernia surgery.
The leaf-tailed gecko (Uroplatus fimbriatus) is found on the island of Madagascar.
The research is published in this week’s issue of the Proceedings of the National Academy of Sciences.
Biomimicry, also called biomimetics, describes design inspired by nature.
