ABSTRACT: 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. aegyptiaca oil 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 (δs) was 16.975 emu g-1. Antibacterial activity was measured.
Efficacy of iron oxide nanoparticles against bacterial strains was found in Escherichia
coli (E. coli). All these findings suggest that the nanoparticles synthesized
from B. aegyptiaca oil may be a promising reagent for a wide variety of applications
in biological fields as well as in nanomedicine.
