Abstract
Iron oxide nanoparticles were created in this study using "Iraqi Aloe vera leaf" extract and a green production technology (IONPs). Using UV and visible spectroscopy, the absorption peaks of the synthesized nanomagnetite were obtained at various temperatures, with a visible absorption peak in the range of (245-450), corresponding to the single spherical diffusion. Changes in peak to shorter wave-length (blue) are dependent on parameter difference. X-ray diffraction (XRD) analysis of the sample revealed that the peaks correspond to Fe<sub>3</sub>O<sub>4</sub>. Using the Scherrer formula, the average crystallite size of the generated Fe<sub>3</sub>O<sub>4</sub> NPs was calculated to be 17.23 nm. Energy-dispersive X-ray (EDX) confirmed the stoichiometric ratio of the elements. Value stream mapping (VSM) was used to investigate the magnetic properties of the material. The Fe<sub>3</sub>O<sub>4</sub> NPs displayed ferromagnetic characteristics at room temperature. The zeta potential of the system was found to be -47.73 mV, showing that the microemulsion droplets possessed a negative charge. Using the well diffusion approach, the antibacterial activity of magnetite nanoparticles against -ve (Serratia) and +ve (Staphylococcus aureus) bacteria was examined. Nanoparticles of Fe<sub>3</sub>O<sub>4</sub> exhibited remarkable antibacterial activity against various types of bacteria.
