Antibacterial activity of iron oxide nanoparticles, an
employing B. aegyptiaca oil (L.) Del., was used as natural stabilizer
by modifying a co-precipitation method. In this work, we chose B. aegyptiacaoil as the new surfactant coating
agent, and synthesized B. aegyptiaca oil coating with iron oxide nanoparticles which were characterized with a variety of methods, including Gas Chromatography
(GC) to determine the fatty acids composition of the seeds oil, Fourier Transform-Infrared Spectroscopy (FTIR), Transmission Electron
Microscopy (TEM) equipped with Energy Dispersive Spectroscopy (EDS), X-ray Powder
Diffractometer (XRD) and Vibrating Sample Magnetometer (VSM). In antibacterial studies,
disk diffusion susceptibility test was used to measure efficacy of iron oxide nanoparticles
against Gram-positive bacteria Staphylococcus aureus (S. aureus), Bacillus subtilis(B. subtilis) and Gram-negative bacteria Escherichia
coli (E. coli) in terms of zone inhibition. The B. aegyptiaca coated on the surface of iron oxide nanoparticles; its particle size was found to
be nanoscale below 50 nm, and the magnetization (δ
