Abstract
In this study, silver-palladium surfaces and silver-bearing stainless steels were designed and investigated
focusing on electrochemical principles to form inhibiting effects on planktonic and/or biofilm bacteria in
water systems. Silver-resistant Escherichia coli and silver-sensitive E. coli were used for the evaluation of
inhibiting effects and the inhibiting mechanism. For silver-palladium surfaces combined with bacteria
in media, the inhibiting effect was a result of electrochemical interactions and/or electrical field, and in
some specific media, such as ammonium containing, undesired silver ions release can occur from their
surfaces. For silver-bearing stainless steels, the inhibiting effect can only be explained by high local silver
ions release, and can be limited or deactivated dependent on the specific environment.
