“…Thus, considerable attempts were made to develop economical, highly sensitive, fast and reliable non-enzymatic glucose sensors [7]. The enzyme-free detection of glucose on noble metals, thin film alloys, and metallic nanoparticles was extensively explored; however, these sensors undergo surface poisoning by adsorbed intermediates, leading to their poor sensitivity, selectivity, and stability [8][9][10]. Nevertheless, non-enzymatic electrochemical glucose sensors based on carbon nanomaterials, particularly carbon nanotubes and graphene, have attracted huge attention due to their unique properties including high surface area, chemical and electrochemical stability, exceptional electrical conductivity, superior biocompatibility, and ease of modification [11,12].…”

<p class="PaperAbstract">Novel polyaniline/zinc oxide/multi-walled carbon nanotube (PANI/ZnO/MWCNT) ternary nanocomposite was fabricated as a non-enzymatic glucose biosensor. Thermal chemical vapor deposition (CVD) process was employed to synthesize vertically aligned MWCNTs on stainless steel substrates coated by Co catalyst nanoparticles. In order to fabricate sensitive and reliable MWCNT-based biosensors, nanotubes density and alignment were adjusted by varying the CVD reaction time and cobalt sulfate concentration. The fabricated nanotubes were modified by ZnO particles through the potentiostatic electrodeposition technique. Optimal electrodeposition potential, electrodeposition time, and electrolyte concentration values were determined. The optimized ZnO/MWCNT nanocomposite was reinforced by polyaniline (PANI) nanofibers through the potential cycling technique, and the morphology, elemental composition, and phase structure of the fabricated nanocomposites were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD), respectively. The sensing mechanism of the PANI/ZnO/MWCNT electrode for the electrochemical detection of glucose was investigated, and the limit of detection and sensitivity values of the designed sensor were determined. The fast response time of the ternary nanocomposite-based sensor as well as its satisfactory stability and reproducibility, makes it a promising candidate for non-enzymatic detection of glucose in biomedical, environmental, and industrial applications.</p>

“…A nano-porous Pt electrode is a 2D or a 3D porous film with nanosized pores usually produced using surface templated electrodeposition [ 164 ] and selective dealloying [ 165 ]. The pioneering work of Park et al [ 166 ] demonstrated the potential of using nano porous Pt for non-enzymatic glucose sensing applications and this was followed by several other studies on Pt film electrodes [ 147 , 158 , 159 ]. Lee et al [ 147 ], developed a prototype of a disposable non-enzymatic blood glucose sensing strip, using nano porous Pt as an electrode material mixed with poly(vinyl acetate) acting as a binding material.…”

The detection of glucose is crucial in the management of diabetes and other medical conditions but also crucial in a wide range of industries such as food and beverages. The development of glucose sensors in the past century has allowed diabetic patients to effectively manage their disease and has saved lives. First-generation glucose sensors have considerable limitations in sensitivity and selectivity which has spurred the development of more advanced approaches for both the medical and industrial sectors. The wide range of application areas has resulted in a range of materials and fabrication techniques to produce novel glucose sensors that have higher sensitivity and selectivity, lower cost, and are simpler to use. A major focus has been on the development of enzymatic electrochemical sensors, typically using glucose oxidase. However, non-enzymatic approaches using direct electrochemistry of glucose on noble metals are now a viable approach in glucose biosensor design. This review discusses the mechanisms of electrochemical glucose sensing with a focus on the different generations of enzymatic-based sensors, their recent advances, and provides an overview of the next generation of non-enzymatic sensors. Advancements in manufacturing techniques and materials are key in propelling the field of glucose sensing, however, significant limitations remain which are highlighted in this review and requires addressing to obtain a more stable, sensitive, selective, cost efficient, and real-time glucose sensor.

“…8,9 Thus, considerable attention has been paid to develop non-enzyme glucose sensors. Especially, Pt binary NPs, including Pt/Pd, 16 Pt/Ag, 18 Pt/Ni 19 and Pt/Cu, 20 have been explored to fabricate non-enzyme glucose sensors. Therefore, the key issue for developing reliable non-enzyme glucose sensors is to explore proper materials that could effectively facilitate electrochemical oxidation and reduction of glucose with strong anti-interference ability.…”

Herein, an ultrasensitive and reliable nonenzymatic electrochemical glucose sensor has been developed, which is based on mesoporous Au/Pt nanodendrites prepared by a facile route aided by ultrasonication under mild conditions. The fabricated glucose sensor is capable of detecting glucose with a wide linear region of 0.01-100 mM and an ultralow detection limit of 1 nM. The higher sensitivity and catalytic properties can be attributed to the mesoporous structures facilitating the mass diffusion rate and favoring the Pt surfaces accessible to reaction media, and the resulting high electroactive surface area of Au/Pt nanodendrites modified electrodes.
