STRUCTURAL AND OPTICAL PROPERTIES OF MAGNETITE NANOPARTICLES PREPARED BY GREEN METHOD FOR BIOPHYSICS APPLICATIONS

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 wavelength (blue) are dependent on parameter difference. X-ray diffraction (XRD) analysis of the sample revealed that the peaks correspond to Fe3O4. Using the Scherrer formula, the average crystallite size of the generated Fe3O4 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 Fe3O4 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 Fe3O4 exhibited remarkable antibacterial activity against various types of bacteria. © 2024 by Begell House,.
