'Sharklet' is a material used in the hulls of ships that inhibits bacterial growth. It was inspired by shark's skin. From their homepage: > Sharklet is the world’s first technology to inhibit bacterial growth through pattern alone. The Sharklet surface is comprised of millions of microscopic features arranged in a distinct diamond pattern. The structure of the pattern alone inhibits bacteria from attaching, colonizing and forming biofilms. Sharklet contains no toxic additives or chemicals, and uses no antibiotics or antimicrobials.
