Facile green synthesis of Ag-doped ZnO/CaO nanocomposites with Caccinia macranthera seed extract and assessment of their cytotoxicity, antibacterial, and photocatalytic activity.

The current paper exhibited a green method for the manufacture of Ag-doped ZnO/CaO nanocomposites (NCPs) by the usage of Caccinia macranthera seed extract, zinc, calcium, and silver salts solution, for the first time. The chemical structure of NCPs was studied by the FT-IR technique. The XRD pattern shows a crystallite structure with an Fm3m group space and particle size of about 23 nm.
