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.

“…Various methods, including the application of chemical coupling agent coatings, electrochemical ablation, and sandblasting to roughen the material's surface, are employed to bolster interfacial bonding. [17][18][19][20] Hirahara et al significantly improved the shear strength of polymer/metal composites by implanting glass fibers vertically into the polymer/metal composite interface. 21 Cheng et al reported a substantial increase in the interfacial bond strength of epoxy/Au composites, along with a 75.5% increase in interfacial stress, achieved through the addition of a single membrane molecular layer on the Au surface.…”

Nano‐injection molding technology is an important method for large‐scale production of metal‐polymer composites of various shapes. The mechanical properties of these materials are closely related to the interfacial process. In this work, polyphenylene sulfide (PPS) and copper (Cu) were selected as candidate polymer and metal materials, and constructed four different polydopamine (PDA) coatings, including monomer, dimer, linear tetramer, and cyclic tetramer, to modify metal surfaces. The molecular dynamics simulations were launched to investigate the interaction behavior of heterogeneous interfaces during nano‐injection molding and the mechanism by which polydopamine affects the adhesion behavior at the copper‐polyphenylene sulfide interface. Results showed that the addition of polydopamine caused the polymer chains to form many anchor points on the contact surface, which inhibited the wall‐slip behavior of the polymer and led to a mushroom‐like movement of the polymer on the wall surface. The interfacial energy, filling rate data revealed that polydopamine contributes to the enhancement of interfacial adhesion properties, and the polydopamine dimer structure is the most effective of the four configurations. The enhancement of interfacial adhesion mainly originates from the enhancement of non‐bonding interactions and entanglement anchoring between PPS‐PDA.Highlights Polydopamine coating inhibits polymer slip behavior in nano‐injection molding. Polydopamine enhances bond strength of metal‐polymer composites effectively. Dopamine dimers have better adhesion properties than other structural dopamine. Polydopamine coating alters the adhesion mechanism at heterogeneous interfaces. The interface failure mode was closely related to the stress loading mode.

“…Also, the enzymatic sensors have drawbacks regarding long-term stability . So, scientists have paid significant attention to developing enzyme-free biosensors based on metal oxides, − metal and metal-doped nanoparticles, − and noble metals. − The effectivity of these materials depends upon the fabrication of composite electrodes using carbon-based materials like carbon nanotubes − and graphene oxide. − Among different electroactive materials, copper and its oxide-based materials show high activity and sensitivity for glucose oxidation. , Despite these recent developments, some problems like high cost, low abundance, specificity, and a high limit of detection remained unaddressed. Thus, the development of copper-based materials for selective and sensitive nonenzymatic detection of glucose has drawn the attention of scientific communities.…”

To date, the fabrication of multifunctional nanoplatforms based on a porous organic polymer for electrochemical sensing of biorelevant molecules has received considerable attention in the search for a more active, robust, and sensitive electrocatalyst. Here, in this report, we have developed a new porous organic polymer based on porphyrin (TEG-POR) from a polycondensation reaction between a triethylene glycol-linked dialdehyde and pyrrole. The Cu(II) complex of the polymer Cu-TEG-POR shows high sensitivity and a low detection limit for glucose electro-oxidation in an alkaline medium. The characterization of the as-synthesized polymer was done by thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, and 13C CP-MAS solid-state NMR. The N2 adsorption/desorption isotherm was carried out at 77 K to analyze the porous property. TEG-POR and Cu-TEG-POR both show excellent thermal stability. The Cu-TEG-POR-modified GC electrode shows a low detection limit (LOD) value of 0.9 μM and a wide linear range (0.001–1.3 mM) with a sensitivity of 415.8 μA mM–1 cm–2 toward electrochemical glucose sensing. The interference of the modified electrode from ascorbic acid, dopamine, NaCl, uric acid, fructose, sucrose, and cysteine was insignificant. Cu-TEG-POR exhibits acceptable recovery for blood glucose detection (97.25–104%), suggesting its scope in the future for selective and sensitive nonenzymatic glucose detection in human blood.
