GREENSYNTHESIS, CHARACTERIZATION, ANTIOXIDANT AND ANTIBACTERIAL ACTIVITY OF SILVER NANOPARTICLES SYNTHESIZED WITH NIGELLA SATIVA SEED EXTRACT

Abstract

In this study, a novel technique for synthesizing silver nanoparticles (AgNPs) prepared from Nigella Sativa (NS) extract is presented. Because NS functions as a very effective stabilizing and reducing agent due to highly metabolized substances such flavonoids, terpenoids, proteins, etc., NS extract in the process is more favorable than other methods. These substances, which have reducing and stabilizing characteristics, cause the formation of AgNPs. Different characterizing techniques, such as UV-Vis, X-ray diffraction, and Fourier transform infrared spectroscopy, were used to examine the as-obtained AgNPs (FTIR). According to XRD data, well-crystallized nanoparticles of lower sizes were formed. 450 nm was discovered to have the highest UV-Vis absorption. Research has been done on the antioxidant and antibacterial properties of silver nanoparticles.
