“…However, a high cost of enzymes, instability, critical operating condition and limited life time of the sensors are the major drawbacks . Thus, several types of non‐enzymatic glucose biosensors including a variety of noble metallic materials (Pt, Pd, and Au) and their alloys have been proposed and developed . But the high cost of several noble metals may limit their commercial applications.…”

In this study, a low‐cost, disposable, sensitive and selective electrochemical sensor was developed for glucose determination, which is based on a pencil graphite electrode (PGE) modified with nickel hydroxide. Cyclic voltammetry was used to deposit nickel on PGE. The morphology and composition of the unmodified and modified PGE electrodes were characterized by field‐emission scanning electron microscopy (FE‐SEM), atomic force microscopy (AFM) and energy‐dispersive X‐ray spectroscopy (EDX). The performance of the as modified electrode towards the electrooxidation of glucose in alkaline media was evaluated with cyclic voltammetry and amperometry techniques. A linear relationship between the concentration of glucose and oxidation peak currents was observed in two concentration ranges of 0.004–3.5 mM and 3.5–9.0 mM. The detection limit was 2 μM at signal‐to‐noise ratio of 3. In addition to a fast response time (<2 s), the proposed sensor preserved 93 % of its original response towards glucose after 28 days. Also, the sensor showed a good reproducibility and high selectivity for glucose oxidation in the presence of common interfering species. The use of Ni(OH)2/PGE sensor was successfully tested in the determination of glucose in human blood serum for the first time in the literature.

“…The electrocatalytic performance of Pd/C 3 N 4 -C is~50% higher than Pd/C. Besides the activity for GOR, the Pd/C 3 N 4 -C shows competitive glucose-sensing performance compared to some other electrocatalysts reported recently [10][11][12][13][14][15][16][17][18] (Table 1). This confirms that Pd/C 3 N 4 -C is indeed a good electrocatalyst for GOR.…”

Porous coral-like Pd/C3N4-C nanocomposites are fabricated by a simple one-pot chemical reduction method. Their electrocatalytic performance is ~50% higher than a carbon-loaded palladium electrocatalyst (Pd/C) in alkaline media. This confirms that the glucose electrooxidation and sensing performance of a Pd/C can be improved by the synergy of graphitic carbon nitride (C3N4), though C3N4 exhibits poor electrical conductivity. Compared to Pd/C, the size of Pd nanoparticles in Pd/C3N4-C decreases. As a result, the activity of Pd/C3N4-C is enhanced due to the higher dispersion and the synergistic effect. Pd/C3N4-C presents a rapid response and high sensitivity to glucose. The sensitivity for glucose sensing at Pd/C3N4-C is 3.3 times that of at Pd/C in the range of 0.001–10 mM. In the lower range of 0.001–1 mM, the sensitivity at Pd/C3N4-C is ~10 times greater than Pd/C.

“…Such a sensor displayed a dynamic range from 0.015 to 6.95 mM with a sensitivity of 1.921 mA/cm 2 ·mM and a detection limit of 10 μM [37]. Shen et al employed a bi-metallic compound of Pd-Au clusters coated with multiple layers of chitosan [38]. The multiple chitosan layers prevented the Pd-Au cluster from leaching out, thereby improving the stability of glucose sensor.…”

Glucose biosensors have received significant attention in recent years due to the escalating mortality rate of diabetes mellitus. Although there is currently no cure for diabetes mellitus, individuals living with diabetes can lead a normal life by maintaining tight control of their blood glucose levels using glucose biosensors (e.g., glucometers). Current research in the field is focused on the optimization and improvement in the performance of glucose biosensors by employing a variety of glucose selective enzymes, mediators and semipermeable membranes to improve the electron transfer between the active center of the enzyme and the electrode substrate. Herein, we summarize the different semipermeable membranes used in the fabrication of the glucose biosensor, that result in improved biosensor sensitivity, selectivity, dynamic range, response time and stability.
