Deposition of antibacterial nanocomposite films using an atmospheric pressure nonequilibrium plasma jet

摘要

In this work, silver nanocomposite films have been deposited using an atmospheric pressure plasma jet system. The plasma jet was characterized using optical emission spectroscopy. The methods of SEM, XPS and GD-OES were implemented for the morphology and stoichiometry of the composite films. The result reveals the morphology and stoichiometry of the films can be tailored during the process. Antibacterial characterization of the films were performed using Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) strains, which show the effective antibacterial activity of the coatings and indicating the fabrication of the nanocomposite films using atmospheric pressure plasma process represents a feasible way for addressing device related infection.
