Biogenic Synthesis of Zinc Oxide Nanoparticles Using Saponaria officinalis L., Characterisation and Antibacterial Activities

Abstract

The bioactivity exhibited by nanoparticles is of great interest by researchers worldwide.Phytogenic synthesis of zinc oxide nanoparticles (ZnO NPs) has been an environmentally friendly approach due to its low toxicity and biological potential.Today, ZnO NPs are frequently the subject of research due to their usability in many different fields such as biomedicine, water treatment, environmental improvement, and their applicability in the food industry and cosmetic products.It is known that ZnO produced by biosynthesis methods exhibits various nanostructures with antimicrobial, antioxidant, and anticancer properties.For this reason, studies on the antioxidant and antibacterial activity of ZnO NPs produced by green synthesis methods are increasing day by day.In this study, the biosynthesis of ZnO NPs was carried out by evaluating the root parts of the Saponaria officinalis plant with high polyphenol content used in the food industry, bread making, and soap making in the cosmetics sector.Nanoparticle characterizations were performed by UV-VIS absorption spectroscopy, FT-IR, XRD, and SEM analysis.These Green-ZnO NPs were shown to have antibacterial activity against the tested bacterial strains.
