Description
Summary:In this study, silver-decorated cerium oxide (Ag@CeO<sub>2</sub>) nanoparticles were synthesized through a simple mixing and pyrolysis process to enhance their antioxidant and antitumor properties. The synthesis methods for Ag@CeO<sub>2</sub> were optimized, resulting in nanoparticles with varying antioxidant activities. Notably, the embedding of Ag nanoparticles within CeO<sub>2</sub> during pyrolysis significantly improved the antioxidant activity and stability of the nanoparticles, leading to enhanced antitumor effects. The Ag@CeO<sub>2</sub> nanoparticles exhibited strong cytotoxicity against tumor cells (MCF-7) while maintaining low toxicity toward normal cells (HUVECs). These properties, combined with their ability to modulate mitochondrial membrane potential, position Ag@CeO<sub>2</sub> as a promising candidate for electrochemical therapy (ECT). This study highlights the antioxidant potential and the potential of Ag@CeO<sub>2</sub> nanoparticles in tumor treatment and provides new insights into the application of nanomaterials in ECT.
