Non-enzymatic sensing has been in the research limelight, and most sensors based on nanomaterials are designed to detect single analytes. The simultaneous detection of analytes that together exist in biological organisms necessitates the development of effective and efficient non-enzymatic electrodes in sensing. In this regard, the development of sensing elements for detecting glucose and hydrogen peroxide (H2O2) is significant. Non-enzymatic sensing is more economical and has a longer lifetime than enzymatic electrochemical sensing, but it has several drawbacks, such as high working potential, slow electrode kinetics, poisoning from intermediate species and weak sensing parameters. We comprehensively review the recent developments in non-enzymatic glucose and H2O2 (NEGH) sensing by focusing mainly on the sensing performance, electro catalytic mechanism, morphology and design of electrode materials. Various types of nanomaterials with metal/metal oxides and hybrid metallic nanocomposites are discussed. A comparison of glucose and H2O2 sensing parameters using the same electrode materials is outlined to predict the efficient sensing performance of advanced nanomaterials. Recent innovative approaches to improve the NEGH sensitivity, selectivity and stability in real-time applications are critically discussed, which have not been sufficiently addressed in the previous reviews. Finally, the challenges, future trends, and prospects associated with advanced nanomaterials for NEGH sensing are considered. We believe this article will help to understand the selection of advanced materials for dual/multi non-enzymatic sensing issues and will also be beneficial for researchers to make breakthrough progress in the area of non-enzymatic sensing of dual/multi biomolecules.

“…Due to its simplicity, fast response, and easy miniaturization, an electrochemical method has been considered as the best for glucose and H 2 O 2 determination. ,− ,− Generally, the electrochemical biosensor is always working with the glucose oxidase (GOx) enzyme by virtue of its high selectivity and sensitivity. , However, the most common and serious problems for the enzymatic glucose sensor are its poor long-term stability, reproducibility, sensitivity to the environment, complicated immobilization procedure, and high cost of enzymes . Therefore, intense efforts have been devoted to the development of an economically viable and interference-free non-enzymatic sensor with high reproducibility that is free of interference and reliably fast that has been echoed by several researchers.…”

Identifying a non-enzymatic sensor electrocatalyst for the accurate determination of biomolecules is a paramount task. The weird morphology of the nanomaterial may exhibit the remarkable activity to enhance the sensitivity of the electrode, and hence, tuning the shape of the nanomaterials is one of the important criteria for electrochemical sensors. Thus, this study sought to fabricate a non-enzymatic sensor with different CuO morphologies by an eco-friendly and facile approach. Different surfactant-free CuO nanostructures were fabricated on the highly conductive flexible aluminum-carbide substrate for the electrochemical assessment of glucose and H2O2 in human fluids. The CuO nanostructures were initially electrodeposited at −0.1, −0.3, −0.5, and −0.7 V and then calcined in air at 120 °C for 2 h. Different CuO nanostructures with a polygonal and cactus-like morphology were observed in scanning electron microscopic images. The as-fabricated electrodes were also characterized by X-ray diffraction (XRD), Xray photoelectron spectroscopy, and electrochemical impedance spectroscopy analysis.Texture coefficients (TC) of different CuO nanostructures were calculated from XRD analysis, and the CuO nanostructures grown at −0.5 V exhibited the highest TC with their texture along the (022) plane. The electrodes grown with different CuO nanostructures exhibited shapedependent electrocatalytic activity against glucose and H2O2, and the cactus-like CuO nanostructures grown at −0.5 V showed superior electrochemical behavior compared to that of the other nanostructures by showing superior sensitivities of 3892.6 and 2015.7 μA mM-1 cm-2, respectively, against glucose and H2O2. In addition, the sensor grown with a cactus-like CuO nanostructure exhibited high selectivity, storage capability, and good practicability. This sensor proved to be practical by determining glucose and H2O2 levels in human fluids. It is believed that the proposed electrochemical sensor will have a strong impact in the dual in-line sensing of biomarkers in both biological and clinical fields in the near future.
