Green synthesis and characterization of Camellia sinensis mediated silver nanoparticles for antibacterial ceramic applications

This study explores the green synthesis and characterization of silver nanoparticles (Ag NPs) mediated by Camellia sinensis extract for their potential antibacterial applications in ceramics. The objective is to develop a sustainable approach to fabricate effective antibacterial nanomaterials that could enhance the performance of ceramic materials. Utilizing a simple synthesis method, the bio-reduction potential of tea extract was employed to produce monodisperse Ag NPs. Various characterization techniques, including UV-Vis spectroscopy, X-ray diffraction, and scanning electron microscopy, were used to analyze the formation and properties of the nanoparticles. The antibacterial efficacy of the synthesized Ag NPs was evaluated against both gram-positive and gram-negative bacterial strains, showing significant inhibition of bacterial growth. The results indicate that the incorporation of Ag NPs into ceramic glaze enhances the antibacterial properties of the material, making it a promising solution for applications in ceramic industries. This research not only highlights the effectiveness of plant-mediated biosynthesis of nanoparticles but also suggests their practical application in preventing bacterial proliferation in ceramic products.
