enhancing the antimicrobial properties copper oxide shell with the magnetic mesoporous core-shell

In this work, magnetic fe3o4@mcm-41/cuo nanocomposite was preparation of iron oxide magnetite nanoparticles and development of mcm-41 mesoporous shells on the surface of iron oxide magnetite after fe3o4@mcm-41 was organofunctionalized and finally formation cuo shells with thickness ~ 25-30 nm in the surface of fe3o4@mcm-41-nh2 core-shell. the properties of prepared magnetic core-shell were characterized by transmission electron microscopy (tem), x-ray diffraction (xrd), nitrogen adsorption–desorption measurement and vibration sample magnetometer (vsm). the applicability of the synthesized core-shell was tested as an antimicrobial agent against gram-positive and gram-negative bacteria. it was showed that the fe3o4@mcm-41@cuo act as an ideal antimicrobial agent in compared with that of the pure copper oxide and fe3o4@cuo.
