This is one of what biologists and physicists at Bremen University of Applied Sciences did when they set out to develop a new protective paint for ship hulls. Like conventional paints, it needed to prevent the ship from becoming encrusted with mussels, barnacles and other subaquatic organisms, but to do so without toxins. The researchers drew their inspiration from sharks, whose skin is densely covered with tiny moveable “teeth” called denticles. While the shark is swimming and the denticles are moving along with the currents, subaquatic organisms have no chance of clinging to it. “We were able to use silicon and granulates to recreate the roughness and elasticity of shark skin. Now we have a biocide-free anti-fouling paint”, says Antonia Kesel who is responsible at the Bremen University of Applied Sciences:for the degree courses in bionics and the associated Biomimetics-Innovation-Centre .
