Nanoglue Sticks Underwater

Bandages might stay put even after a swim, thanks to a new adhesive developed by researchers at Northwestern University. The glue not only works well on wet surfaces, but it can also be pulled off and reused more than a thousand times.
The nanoglue is made of 400-nanometer-wide silicone pillars covered with a polymer that mimics the adhesive proteins found in mussels. In addition to bandages, the new material could be used in drug-delivery patches and in adhesive tapes to close surgical wounds, says Phillip Messersmith, a biomedical-engineering professor at Northwestern University, who reported the glue in Nature this week.
