In Situ Green Synthesis of CoO@ZnO Core-Shell Nanoparticles Using Leaf Extract: Antibacterial and Antioxidant Studies.

Investigating and synthesizing potent antibacterial NPs using biological methods is highly preferred, and it involves nontoxic, cost-effective, and environmentally friendly chemicals and methods. Antibiotic drug resistance and oxidative stress have become a serious public health issue worldwide. Hence, the key objective of this study was to biologically synthesize and characterize the potent antibacterial CoO@ZnO core-shell nanoparticles for the antibacterial application.
