Green Biological Synthesis, Properties of Magnetite Nanoparticles (Fe₃O₄ Nps) Using Qazwan Seeds Extract as Antimicrobial Agent

This research reports the green and environmentally friendly preparation of the magnetite nanoparticles (Fe₃O₄ NPs) using aqueous extract of Qazwan (Pistacia atlantica) seeds. The green Fe₃O₄ NPs were characterized with different characterization techniques such as Ultraviolet-Visible (UV-vis) Spectrometer, Energy Dispersive X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), and Field Emission Scanning Electron Microscopy (FESEM) equipped with Energy Dispersive Spectroscopy (EDS), and Fourier Transform Infrared (FTIR) spectrophotometer. The XRD, TEM, and SEM demonstrate the generation of crystalline green Fe₃O₄ NPs with mean diameter of 14-15 nm. The UV-Vis spectrum and FTIR were used to identify the biomolecules in the Qazwan seed extract which act as capping, reducing and efficient stabilizer agent for synthesized green Fe₃O₄ NPs. Additionally, the antibacterial activity and antifungal of biologically synthesized nanoparticles was proved against gram positive (Enterococcus faecalis), gram negative (E. coli, Pseudomonas aeruginosa, Acinetobacter baumanni and Klebsiella pneumonia)), and Candida albicans pathogenic fungi strains.
