From: Gum arabic modified Fe3O4 nanoparticles cross linked with collagen for isolation of bacteria
X-ray diffraction and magnetic nature of material. The XRD pattern of as-synthesized Fe3O4 nanoparticles clearly demonstrates the formation of nanocrystalline Fe3O4. The inset (upper) of figure shows the appearance and color of as-synthesized powder. The other inset (lower one) of the figure shows photograph of drawn nano particles to the sidewall of the vial by an external magnet, dispersed in water.
