      abstract     = {The development of antibacterial implant surfaces is a
                      challenging task in biomaterial research. We fabricated a
                      highly antibacterial bimetallic platinum (Pt)/silver(Ag)
                      nanopatch surface by short time sputtering of Pt and Ag on
                      titanium. The sputter process led to a patch-like
                      distribution with crystalline areas in the nanometer-size
                      range (1.3–3.9 nm thickness, 3–60 nm extension).
                      Structural analyses of Pt/Ag samples showed Ag- and Pt-rich
                      areas containing nanoparticle-like Pt deposits of 1–2 nm.
                      The adhesion and proliferation properties of S. aureus on
                      the nanopatch samples were analyzed. Consecutively sputtered
                      Ag/Pt nanopatches (Pt followed by Ag) induced enhanced
                      antimicrobial activity compared to co-sputtered Pt/Ag
                      samples or pure Ag patches of similar Ag amounts. The
                      underlying sacrificial anode mechanism was proved by linear
                      sweep voltammetry. The advantages of this nanopatch coating
                      are the enhanced antimicrobial activity despite a reduced
                      total amount of Ag/Pt and a self-limited effect due the
                      rapid Ag dissolution.},
