Glucose sensors have been extensively developed because of their broad applications, especially in diabetes diagnosis. Up to date, electrochemical enzymatic glucose are commonly used daily life for detection and commercially successful as glucose-meters they exhibit excellent selectivity, high reliability, could be handled under physiological pH conditions. However, considering some intrinsic disadvantages enzymes, such fabrication cost poor stability, non-enzymatic attracted increasing research interest recent years due low cost, prompt response, limit. Furthermore, the development nanotechnology has also offered new opportunities construct nanostructured electrodes sensing applications. With distinguished advantages, metal oxides garnered extensive effort cost-effective with sensitivity quick response determination via oxidation. Hence, this review summarizes advances based on different (such ZnO, CuO/Cu2O, NiO, Co3O4, MnO2, etc.) nanocomposites. Additionally, a brief prospective is presented sensors.
