Using a two step replication process, porous gold or nickel films could be obtained from anodic aluminum oxide films having two different hole diameters in its interior. The specifically tailored nanostructure of the starting material could be replicated to form through-hole nickel or gold membranes with an ordered linear structure having diameters of either 120 nm or 40 nm on one side and 57 or 23 nm respectively on the other side of the film.
