Bacterial responses to <i>Ephedra aphylla</i> stem extract and green-synthesized Ag-TiO₂ and Ag-SeO₂ core/shell nanocomposites: unveiling antimicrobial and antioxidant properties.

ABSTRACT: This study reports an efficient and green protocol for the green synthesis of Ag-TiO₂ and Ag-SeO₂ nanocomposites using the extracted stems of Ephedra aphylla. Results of spectroscopic and analytical analyses confirmed the successful synthesis, stability, and crystalline nature of the nanomaterials. The phytochemical profile and antioxidant and antimicrobial activities of the E. aphylla extract and the nanocomposites were also studied. E. aphylla extract and both the nanomaterials exhibited significant levels of active phytochemical compounds. These compounds contributed to their potent antioxidant activity, with E. aphylla extract and Ag-TiO₂ NC demonstrating the highest antioxidant activity. Besides, Ag-SeO₂ NC displa
