Marine Fouling Illustration (IMAGE) Johannes Gutenberg Universitaet Mainz Caption This is an illustration of the mode of action of bioinspired underwater paints: Like the natural enzyme vanadium bromoperoxidase cerium dioxide nanoparticles act as a catalyst for the formation of hypobromous acid from bromide ions (contained in sea water) and small amounts of hydrogen peroxide that are formed upon exposure to sun light yielding reduced biofilm formation.
