Abstract(#br)Despite numerous preventive strategies on bacterial adhesion, pathogenic biofilm formation remained the major cause of medical device-related infections. Bacterial interference is a promising strategy that uses pre-established biofilms of benign bacteria to serve as live, protective coating against pathogen colonization. However, the application of this strategy to silicone urinary catheters was hampered by low adherence of benign bacteria onto silicone materials.

Abstract(#br)Very thin polydimethylsiloxane (PDMS)-layer with a mean thickness of 3–5\u003cce:hsp sp=\"0.25\"/\u003enm was formed on Cu particles by using thermal evaporation of PDMS at 200\u003cce:hsp sp=\"0.25\"/\u003e°C under nitrogen atmosphere. Using X-ray photoelectron spectroscopy and FT-IR, it was shown that the dimethylsiloxane framework was sustained after evaporation of PDMS and its deposition on Cu particles.
