Core-shell structured silver-ferrite nanoparticles for antibacterial action and magnetic removal of bacteria from aqueous media.

ABSTRACT: In this work, we synthesized antibacterial core-shell structured magnetic nanoparticles with silver particles as the core and nickel-ferrite or cobalt-ferrite crystallites as the shell using solvothermal method. The prepared ferromagnetic amine-functionalized Ag/NiFe₂O₄ and Ag/CoFe₂O₄ particles had a saturation magnetization (Ms) of 40 emu/g and 37 emu/g, respectively, and were therefore easily separated from aqueous media by magnetic field, thus making them excellent magnetic adsorbents. The produced core-shell particles had mean diameters of 276 ± 70 nm (Ag/CoFe₂O₄) and 337 ± 109 nm (Ag/NiFe₂O₄). Due to their silver content, these particles showed outstanding antibacterial activity against Gram-positi
