Using Nigella Sativa Seeds Extract for the Biosynthesis, Characterization and Antimicrobial Activity of CuO Nps

Abstract

Researchers are interested in green technology because it is a low-risk, eco-friendly and affordable way to biosynthesize nanoparticles (NPs). Copper nitrate trihydrate and Nigella sativa extract were used as a reducing and capping agent during the manufacture of copper oxide (CuO) NPs in this investigation. The biosynthesized CuO NPs were characterized using X-ray diffractometer, transmission electron microscopy, UV–Vis spectroscopy, scanning electron microscopy and Fourier transform infrared (FTIR) spectroscopy. The good crystalline nature perfectly matches the monoclinic structure of bulk CuO. The results obtained from TEM also showed that CuO NPs were semi-spherical in shape, while the zeta potential characterization indicated that the prepared particles have low stability. Moreover, CuO NPs showed good antimicrobial activity.

“…Nanomaterials are of significant importance in several scientific disciplines, including the sciences such as physics, chemistry, materials science, medicine, and biological sciences due to their wide-ranging applications [1,2]. Metal oxide nanoparticles have garnered significant attention from researchers owing to their extensive applicability in many fields such as nanocatalysts, industrial catalysts, chemical sensing devices, medicinal applications, antimicrobials, semiconductors, microelectronic, disinfection, opacifiers, fillers, and cosmetic [3][4][5]. According to the preparation method, the nanoparticles can either be distributed and aggregated or isometric and inhomogeneous [6].…”
