In this work, ZnO nanorods (NRs) were fabricated onto ZnO seed coated glass substrate by hydrothermal method. ZnO NRs successfully applied for the development of non-enzyme glucose. The structural study of ZnO NRs was per-formed by scanning electron microscopy (SEM) and X-ray differaction (XRD) techniques. ZnO NRs are highly dense, demonstrate the hexagonal wurtzite structures of nanorods have a preferential growth with c-axis and possess good crystalline quality. ZnO NRs sensitivity of the sensor to glucose oxidation was 37.7 μA mM−1 cm−2. The ZnO nanorods modified electrode showed a greatly enhanced electrocatalytic property toward glucose oxidation, can be attributed to the large active area supported, as well as an excellent anti-interference and a good stability.
