A novel ECL biosensor is fabricated by immobilizing Ru(bpy) 3 2+ nanowires (RuNWs) onto a glassy carbon electrode (GCE) surfaces with reduced graphene oxide (RGO)‐Nafion composite film. The sensor exhibits high sensitivity and long‐term stability, and shows a wide linear response range and low detection limit for biomolecular analytes. The large electroactive area of the nanowires and the enhancement effect of the RGO play critical roles in the high detection performance of the biosensor.
