Gecko-Inspired Material

File under insanely cool. This from MIT news, the development of patch for internal injuries inspired by gecko lizard. How’s that for biomimicry.

Drawing on some of the principles that make gecko feet unique, the surface of the bandage has the same kind of nanoscale hills and valleys that allow the lizards to cling to walls and ceilings. Layered over this landscape is a thin coating of glue that helps the bandage stick in wet environments, such as to heart, bladder or lung tissue. And because the bandage is biodegradable, it dissolves over time and does not have to be removed.
