In- vitro biosynthesis of concentration-induced nickel oxide nanoparticles for antibacterial applications

Abstract

Biosynthesis of NiO nanoparticles (NiONPs) using Gongronema Latifolium (GL) as a potential reducing agent for antibacterial applications is emplaced in this work. X-ray diffractometer (XRD) analysis confirmed the face-centered cubic of the prepared GL_NiONPs, the scanning electron microscopy (SEM) images showed the spherical image of the sample. Fourier transforms infrared (FTIR) spectroscopy shows the functional group responsible for the reduction processes and UV–visible spectroscopy shows the absorbance potency within the visible range. The antibacterial activity of the samples was carried out on staphylococci aureus and coliform (bacilli) bacteria strains. The results showed reduced cell growth of the bacteria strains and improved the antibacterial activities, especially in the staphylococci aureus strain, which had the highest zone of inhibition. Hence, the formulated sample can serve as a potential antibacterial agent.
