<p>Zinc oxide (ZnO) nanostructures were produced using an anodization method to construct non-enzymatic glucose biosensors. The ZnO nanoparticles’ optical, structural, and morphological characteristics were determined by X-ray diffraction (XRD) and photoluminescence spectroscopy, with the XRD patterns of the ZnO exhibiting a hexagonal phase structure with average crystallite sizes of around 11.46–11.78 nm. Samples with anodization voltages of 2, 4, and 6 V, demonstrated high glucose detection activity with sensitivity values of 1557, 1936, and 2018 µA mM⁻¹ cm⁻² and low limit of detection values of 0.45, 0.34, and 0.62 mM, respectively. The broad linear range for glucose detection is from 0.3 to 0.9 mM. Overall, these findings indicate that ZnO nanoparticles are a potentially effective material for biosensor designs and other biological applications.<?oxy_aq_start??>Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).
