Glucose sensor using periodic nanostructured hybrid 1D Au/ZnO arrays

► Zinc acetate-PVA-Au(III) composites were prepared by simply mixing zinc acetate-PVA and gold(III) chloride trihydrate. ► Hybrid 1D nanostructured Au/ZnO arrays were easily fabricated using surface relief gratings without additional process steps. ► Redox and optical sensor to detect D(+)-glucoses.
