acterial biofilms on medical devices (MDs) can cause deadly infections due to their resistance to antibiotics. Technology to prevent this kind of complication is urgently needed because they impact not only patients? lives but also hospital budgets. In this paper, the creation and testing of an easy to produce antibiofilm (more precisely antibiofouling) coating are described for the first time. This coating can be applied to catheters, prostheses and other plastic pieces, even after they have been manufactured. Rapid and eco-friendly synthesis of nanostructured gold coating was done in situ in just 15 minutes. Complete characterization and microbiological analysis of its antibiofouling capacity are presented. The coating prevents biofilm formation of pathogenic clinical isolates and ATCC strains on medical devices, possibly due to its complex nanostructured gold surface. If the next generation of medical devices is coated with this kind of antibiofouling technology, biofilm-related in
