Fabrication of Au nanowire array for anodic stripping voltammetry determination of trace Pb2+ ions

► Au nanowire arrays were synthesized by galvanostatic deposition within AAO template. ► ANs array achieved higher anodic oxidation current than Au-disc electrode. ► ANs sensors achieved a sensitivity of 1.0952 μA/(μg/L) and a DL of 0.2 μg/L.
