In this work, we present a novel process for fabrication of a silver‐nanoparticle‐modified electrode using silver ion implantation. This method is facile, low‐cost and environmental friendly without the use of any other chemicals. The obtained AgNPs on the electrode surface, which were free from any reagents surrounding or binding to them, showed prominent electrocatalytic activity towards the oxidation of glucose, leading to a nonenzymatic glucose sensor with a wide linear range and a detection limit of 0.5 µM. In addition, the modified electrode also exhibited acceptable reproducibility and long‐term stability.
