Green synthesis, characterization and antibacterial activity of iron oxide nanoparticles derived fromSolanum nigrum leaf extract

In order to create iron nanoparticles, extract from Solanum nigrum was used. By using UV/Vis absorptionspectroscopy, X-ray diffraction spectroscopy, and SEM examination, the produced iron nanoparticles were identified. Iron oxide nanoparticles exhibit a distinctive absorption peak in the UV/Vis spectrum between 200 and 300 nm. Theaverage particle size of magnetite nanoparticles, as determined by the X-ray diffraction method, was found to be 24.1nm. By using the well diffusion method, it was discovered that the synthetic iron nanoparticles have antibacterial action against harmful bacteria such Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, and Klebsiellapneumoniae. This biosynthetic method has been discovered to be economical, environmentally benign, and promisingfor use in a variety of fields. Keywords: Iron nanoparticles, Solanum nigrum, antibacterial activity
