Synergistic peroxidase-like activity of CeO2-coated hollow Fe3O4 nanocomposites as an enzymatic mimic for low detection limit of glucose

Owing to the individual peroxidase-like catalytic activity of CeO2 onto Fe3O4 nanoparticles, Fe3O4@CeO2 yolk-shell nanocomposites was investigated to achieve synergistic catalytic activity.85
