Silver-Doped Zinc Oxide Nanoparticles: A Multifunctional Nanomaterial

Strategic Insights -

Researchers have developed silver-doped zinc oxide nanoparticles that exhibit exceptional photocatalytic, antibacterial, and anticancer properties, while also being reusable and recyclable. These nanoparticles, prepared via the co-precipitation method, showed a hexagonal structure characteristic of zinc oxide. The incorporation of silver metal within the zinc oxide lattice was validated through energy-dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectroscopy (FTIR). The nanoparticles demonstrated remarkable photocatalytic prowess, degrading methylene blue in four cycles, and potent antibacterial efficacy against select pathogens, including Escherichia coli and Staphylococcus aureus. Notably, these nanoparticles also exhibited significant anticancer activity against Hep-G2, a human hepatoma cell line.
