Silver nanowire array sensor for sensitive and rapid detection of H2O2

► Home-made AAO templates were used for fabricating Ag nanowire (Ag NW) arrays. ► Ag NW array electrodes showed excellent electroactivity toward the reduction of H2O2. ► The sensor exhibits high sensibility, good reproducibility, and long-term stability. ► The detection of H2O2 is not influenced by interference compounds.
