new Fe3O4@SiO2@Polyionene/Arsenic acid core–shell-shell magnetite nanoparticle was prepared with co-precipitation method and was used against gram positive and gram negative pathogen. The ionene was easily prepared with reacting DABCO and 1,4-dibromo butane in DMF/Methanol. The polyionene was added to the previous layers and magnetic core–shell nanoparticles (P-MNPs) werefunctionalized. All resulting nanoparticles were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), infrared spectroscopy (FTIR), and vibrating sample magnetometer (VSM). The catalyst was readily recovered by simple magnetic decantation and can be recycled several times with no significant loss of catalytic activity.
