With a facile solvothermal method, Ag@Fe 3 O 4 nanowire was successfully prepared and characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The obtained Ag@Fe 3 O 4 nanowire posses enhanced peroxidase‐like activity with good stability and high absorbance. The optimization of pH, H 2 O 2 concentration and loading capacity were carried out. The result of kinetic analysis indicates that the catalyzed reaction followed a Michaelis‐Menten behavior. The good peroxidase‐like activity makes Ag@Fe 3 O 4 nanowire be promising for real application in biomedicine.
