Gecko Feet Lead to Revolutionary Surgical Tape
Geckos stick to walls using microscopic hairs called setae. Harvard scientists created biodegradable surgical tape with similar nanoscale structures. This tape seals internal wounds after pacemaker placement and dissolves safely within weeks. Rat studies show it cuts scar tissue by half compared to sutures. Patients heal faster with less internal damage. The tape adheres even in wet environments, making it ideal for cardiovascular procedures where traditional closures struggle.
