Abstract In this study, an environment‐friendly, energy‐saving, and useful synthesis of zinc oxide (ZnO) nanoparticles (NPs), titanium oxide (TiO 2 ) NPs, and mixed Zn/TiO x ‐NPs was achieved using underwater pulse discharge plasma. The obtained NPs were characterized by UV spectroscopy, X‐ray diffraction, scanning electron microscopy, and transmission electron microscopy. In the discharge cell, the viscose patch is impregnated with ZnO, TiO 2 , and mixed Zn/TiO x ‐NPs in a one‐step process. The adhesive patch is effective against Escherichia coli , Staphylococcus albicans , and Bacillus subtilis . The viscose patch containing 0.22% Zn/TiO x ‐NPs demonstrated the highest antimicrobial activity. These antimicrobial patches can be used to treat and cover wounds susceptible to infection.
