Diabetes has become a chronic disease that necessitates timely and accurate detection. Among various detection methods, electrochemical glucose sensors have attracted much attention because of low cost, real-time detection, and simple and easy operation. Nonenzymatic biomimetic nanomaterials are the vital part in electrochemical glucose sensors. This review article summarizes the methods to enhance the glucose sensing performance of noble metal, transition metal oxides, and carbon-based materials and introduces biomimetic nanomaterials used in noninvasive glucose detection in sweat, tear, urine, and saliva. Based on these, this review provides the foundation for noninvasive determination of trace glucose for diabetic patients in the future.

transistor, [6] electrochemical glucose sensors with superior selectivity, sensitivity, and portability have aroused great interest of researchers. [7] In the past few decades, most researches have focused on the traditional glucose sensors, which are based on the immobilization of glucose oxidase on various substrates. [8,9] Among them, the catalytic oxidation of glucose is carried out under a certain voltage, and an electrical signal is output. These enzyme-based sensors display good selectivity and high sensitivity in glucose detection, but the enzyme activity is susceptible to pH, temperature, and toxic chemicals. [10] Nonenzymatic glucose sensors mainly depend on the current response of glucose directly oxidized on the surface of nanomaterials modified electrode, which shows higher stability than the enzyme-based glucose biosensor. [11] Therefore, great efforts have been made to develop novel nonenzymatic glucose sensors to solve the instability problem associated with enzyme-based catalysts. The low potential for catalyzing the glucose oxidation is critical for the stability of enzyme-free glucose sensors. Noble metal-based catalysts have been widely investigated for glucose sensing due to their lower redox potential, ranging between 0.1 and 0.5 V versus Ag/AgCl or saturated calomel electrode (SCE) reference electrodes, and high selectivity without interference from maltose, ascorbic, uric acid, and other biomolecules. Benefiting from these advantages, the noble metal-based glucose sensors also possess good stability and reproducibility. [12,13] However, noble metal catalysts with smooth surface and simple structure lack enough active sites, which directly affect the adsorption of glucose molecules and the desorption of glucose oxidation products, and further lead to poor sensitivity and stability of the enzyme-free glucose sensor. [14] Electrocatalytic glucose oxidation is a type of heterogenous catalytic reaction that occurs on the surfaces and interfaces of noble-metal-based nanostructures and electrolytes. It is generally believed that the activity, selectivity, and stability of electrocatalysts are sensitive to the surface and interface, which are not only related to their morphology, structure, and composition, but also closely related to the adsorption strength of reactant molecules or intermediates. [15,16] In this sense, each step should be beneficial to adsorption and desorption, thereby promoting the whole catalytic reaction. Sufficient active sites are the key to catalytic performance, which largely depends on the surface and interface state. In order to improve the catalytic ability of NM catalysts Precise glucose monitoring is needed to meet the growing demand of blood glucose determination in diabetes diagnosis. In spite of good selectivity and high sensitivity of enzyme-based glucose sensors, the activity of enzyme is sensitive to pH and temperature, which makes them unstable in detecting glucose level. Alternatively, nonenzymatic electrocatalysts have attracted intensive attention because o...

“…Hydrogen peroxide (H 2 O 2 ) is an important chemical reagent that plays a vital role in paper bleaching, wastewater treatment, disinfection, chemical synthesis, and energy applications. [1][2][3][4][5][6][7] Today, H 2 O 2 is produced industrially using the anthraquinone process, which involves multi-step hydrogenation and oxidation reactions that are highly energyintensive and unsustainable. 8,9 Photocatalysis (PC) is a promising alternative.…”
