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 ZnONPs; researches are also prominent due to its versatile structure such as biomedical, wastewater treatment, environmental improvement and also its applicability in 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 ZnONPs produced by green synthesis methods are increasing day by day. In this study, the biosynthesis of ZnONPs was carried out by evaluating the root parts of Saponaria officinalis plant with high polyphenol content used in the food industry, bread making and soap making in the cosmetics sector. Characterization of the Nanoparticles synthesiszed were performed by UV-VIS absorption spectroscopy, FT-IR, XRD and SEM analysis. These Green-ZnO NPs were demonstrated to posses antibacterial activity against bacteria strains tested. The results obtained showed that Saponaria officinalis plant extract can be used as a good bioreducing agent for the synthesis of zinc nanoparticles.
