Applications of plasma synthesized ZnO, TiO2, and Zn/TiOx nanoparticles for making antimicrobial wound-healing viscose patches

In this study, an environment-friendly, energy-saving, and useful synthesis of zinc oxide (ZnO) nanoparticles (NPs), titanium oxide (TiO2) NPs, and mixed Zn/TiOx-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, TiO2, and mixed Zn/TiOx-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/TiOx-NPs demonstrated the highest antimicrobial activity. These antimicrobial patches can be used to treat and cover wounds susceptible to infection.

Automated summary

This study achieved the synthesis of zinc oxide (ZnO) nanoparticles (NPs), titanium oxide (TiO2) NPs, and mixed Zn/TiOx-NPs in an environmentally friendly and energy-saving manner using underwater pulse discharge plasma. The obtained NPs demonstrated antimicrobial effectiveness, especially in the viscose patch containing 0.22% Zn/TiOx-NPs, which showed the highest activity against bacteria and can be used to treat and cover wounds susceptible to infection.
