A process for production of an actively antimicrobial surface for a substrate and for use in a biologically dynamic environment, such as for treating and preventing microbial infections, including a film consisting of at least an antimicrobial element and another electrochemically nobler element and which forms multitudinous galvanic cells with electrolyte-containing biological fluids, such as body fluids from wounds, etc., for releasing the antimicrobial element at the surface.

1. A process for the production of an actively antimicrobial surface film on a substrate for use in a biological environment, which comprises the steps of,forming a first layer comprising a first element on a surface of said substrate; texturing said first layer; shadow depositing a second element on the said first layer to provide areas of said layer covered by said second element and areas not covered by said second element, at least one of the first and second elements being antimicrobially active and the other of the first and second elements being electrochemically nobler than said antimicrobially active element, said antimicrobially active element being ionically soluble in electrolytic biological fluid brought into contact with said film.
