Hybrid chitosan-ZnO nanoparticles coated with a sonochemical technique on silk fibroin-PVA composite film: A synergistic antibacterial activity.

The hybrid chitosan-ZnO nanoparticles (C@ZnO NPs) are synthesized and coated on Silk fibroin-polyvinyl alcohol (SF-PVA) composite film by a sonochemical coating process. These are systematically studied for their synergistic antibacterial activity and reported. The coated composite films show the excellent antibacterial activity against Gram-positive and Gram-negative bacteria.
