Schematic process of both passive and active multifunctional properties of Au–Ag JFNF scaffold. Scaffolds containing Au and Au–Ag NPs were put on a mature biofilm surface and irradiated by 808 nm laser. The scaffolds showed complete disruption of the biofilms. After 24 h, regrowth of the biofilm was observed only in the case of the Au-based scaffold, while no growth of the biofilm was observed in the case of the Au–Ag-based scaffold
