A biologically-inhibiting surface based on electrochemical principles has been shown to have a reducing effect on the formation of biofilms in drinking water. The coating consists of silver and another precious metal, which is applied to the surface in small areas with a thickness measured in nanometers. Due to the difference in potentials, the biologically-inhibiting material will act as a galvanic element in contact with an electrolyte. The electrochemical processes taking place at the metal surface seem to exhibit a catalytic oxidation character more than an oligomeric effect from the silver.
