“…For the glucose sensor electrode, selectivity was an important factor affecting its accuracy. Considering that the real blood environment usually contains endogenous interfering substances, such as UA, AA, metal ions, and other sugars, their presence may affect the sensitivity of glucose sensors . Therefore, we used 2 mM glucose and 0.1 mM AA, UA, AP, and sodium chloride (NaCl) as interfering substances to conduct an interference test on glucose.…”

High-entropy alloys have long been used as a new type of alloy material and have attracted widespread concern because of their excellent performance, including their stable microstructure and particular catalytic properties. To design a safer preparation method, we report a novel approach targeting green synthesis, using tea polyphenols to prepare PtPdNiFeCu high-entropy alloy nanoparticles for glucose detection. The fabricated sensors were characterized by transmission electron microscopy and electrochemical experiments. Physical characterization showed that the nanoparticle has better dispersibility, and the average particle size is 7.5 nm. The electrochemical results showed that Tp-PtPdNiFeCu HEA-NPs had a high sensitivity of 1.264 μA mM –1 cm –2 , a low detection limit of 4.503 μM, and a wide detection range of 0 - 10 mM. In addition, the sensor has better stability and selectivity for glucose detection.

“…Obviously, all of them could be oxidized at the target electrode to generate pronounced oxidation peaks that started at potential ca. 0.40 V. The peak potentials of all the polyhydroxy compounds were in the range of 0.55 to 0.65 V where Cu(II) was oxidized to Cu(III) species [28,34]. The results indicated that Cu(III) sites generated on the surface electrode played key role in the electrochemical detection of these polyhydroxy compounds.…”

“…However, they were not suitable for the amperometric detection of CE as the coated materials may fall off during analysis. Since glucose could be detected on cuprous oxide (Cu 2 O)-modified electrodes with high sensitivity [34], it is of high interest to prepare graphene-Cu 2 O hybrid electrode for the measurement of polyhydroxy compounds.…”

An alkaline mixture containing copper(II) spices, graphene oxide and glucose was heated by far infrared radiations to synthesize graphene-cuprous oxide hybrid. The hybrid was blended with mineral oil and packed into tubes to fabricate paste electrodes. The electrodes were coupled with capillary electrophoresis for the detection of polyhydroxy compounds. The sensitivities of them on the hybrid electrodes were significantly enhanced by taking advantages of graphene and cuprous oxide. The contents of polyhydroxy compounds in tobacco method was determined by the electrodes with satisfactory assay results.

“…The second factor is selectivity, which refers to the capacity of non-enzymatic glucose sensors to detect only glucose levels without being contaminated by other substances in the sample, such as ascorbic acid, uric acid, and acetaminophen. [38] After it was built, scientists evaluated how well the NiO nanowire array for glucose sensing performed in the presence of potential substances including ascorbic acid, uric acid, and acetaminophen. The findings showed that the NiO nanowire array had a high selectivity for glucose and little influence from the other chemicals tested.…”

The determination of the body's glucose level is a difficult job that has served as the foundation for substantial research efforts in biosensing applications. Recent advances in material engineering and synthesis methodologies have had a significant influence on the development of enzymatic and non‐enzymatic sensors for glucose detection that may be used in managing diabetes, food technology, and clinical, and bio‐processing applications. The intricate fabrication, detecting principles and phenomena involved, material alterations, and design to improve sensor performance. There is a great need for high‐efficiency, low‐cost blood glucose sensors that may be used on industrial and domestic scales. This review is primarily intended to shed light on the current state of knowledge about the use of graphene. The performance of non‐enzymatic glucose sensors is comprehensively compared with that of enzymatic electrochemical sensors based on graphene. This study will go over the research efforts that have been conducted to build biosensors employing nanostructures such as carbon nanotubes, graphene, metal nanoparticles, metal oxides, and metal sulfides. The manufacturing of the very sensitive enzyme‐free glucose biosensor will be thoroughly discussed. A thorough examination of the use of graphene as a co‐catalyst to improve the sensitivity of electrochemical sensors for glucose detection is also provided.
