“…The procedure of detection of glucose in an alkaline solution using this nickel based sensor was identical to the process described in section 3.2. Differential pulse voltammetry was applied and an anodic peak was obtained at +0.38V versus the thick film printed Ag/AgCl reference electrode [13,14,16], which was also confirmed by Luo's study [21]. Figure 8b shows the differential pulse voltammetry graph for the detection of glucose in 0.1 M NaOH solution using the electrochemically deposited nickel thin film sensor covering the glucose concentration range of 50mg/dL to 200mg/dL.…”

“…The reaction mechanism demonstrated that the alkaline solution oxidized metal catalysts, then glucose reduced the oxidized metal producing gluconic acid [4,5,14,19,21]. Thus, the performance of metallic catalysts, including nickel, platinum and copper for detection of glucose in alkaline solution, were examined and compared with the cuprous oxide thin film sensor.…”

“…Therefore, the detection of glucose using a platinum based sensor was also studied in this research endeavor. The fabrication of the thin platinum film sensor prototype was identical to the process of the thin gold film sensor prototype [12][13][14][15][16] with the only difference that platinum (50nm thickness) was used for the working and the counter electrodes stead of gold. Sputtering physical vapor deposition, laser ablation and thick-film printing technologies were used, and the platinum thin film sensor could also be fabricated by roll-to-roll cost-effective manufacturing process.…”

A cuprous oxide (Cu2O) thin layer served as the base for a non-enzymatic glucose sensor in an alkaline medium, 0.1 NaOH solution, with a linear range of 50-200 mg/dL using differential pulse voltammetry (DPV) measurement. An X-ray photoelectron spectroscopy (XPS) study confirmed the formation of the cuprous oxide layer on the thin gold film sensor prototype. Quantitative detection of glucose in both phosphate-buffered saline (PBS) and undiluted human serum were carried out. Neither ascorbic acid nor uric acid even at a relatively high concentration level of 100mg/dL in serum interfered with the glucose detection, demonstrating the excellent selectivity of this non-enzymatic cuprous oxide thin layer based glucose sensor. Chronoamperometry (CA) and single potential amperometric voltammetry were used to verify the measurements obtained by differential pulse voltammetry (DPV), and the positive results validated that the detection of glucose in a 0.1 M NaOH alkaline medium by DPV measurement was effective. Nickel, platinum and copper are commonly used metals for non-enzymatic glucose detection. The performance of these metal-based sensors for glucose detection using DPV were also evaluated. Cuprous oxide (Cu 2 O) thin layer based sensor showed the best sensitivity for glucose detection among the sensors evaluated.

View full text Add to dashboard Cite

Nitrogen‐doped hollow cobalt oxide nanofibers (Co3O4 NFs) with both glucose catalytic activity and pH sensitivity were fabricated through core‐sheath electrospinning technique, followed by calcination. The as‐developed nitrogen‐doped hollow Co3O4 NFs were thoroughly characterized using various techniques, and then employed to fabricate a dual electrochemical sensor for both pH sensing and glucose sensing. The pH sensitivity of the developed nitrogen‐doped hollow Co3O4 NFs demonstrated a Nernst constant of 12.9–15.9 mV/pH in the pH range of 3.0∼9.0 and 6.8–10.7 mV/pH in the pH range of 9.0∼13.0, respectively. The developed hollow cobalt oxides nanofibers sensor also possesses glucose sensitivity of 87.67 μA mM−1 cm−2, the limit of detection of 0.38 μM (S/N=3), and an acceptable selectivity against several common interferents in non‐enzymatic glucose determination. High accuracy for monitoring glucose in human serum sample was also demonstrated. These features indicate that the as‐synthesized nitrogen‐doped hollow cobalt oxides nanofibers hold great potential in the development of a unique dual sensor for both solid‐state pH sensing and superior non‐enzymatic glucose sensing.

Nanostructured Gold Microelectrodes for Non‐enzymatic Glucose Sensor

A novel, highly stable, selective, and sensitive non‐enzymatic glucose sensor was developed by simple and effective modification procedure. The modification of gold microelectrodes by electrochemically deposited gold nanoparticles resulted in increase of surface area up to 37 %. The nanostructured surfaces of the gold microelectrodes obtained by different modifications were studied by confocal microscopy, atomic force microscopy, and scanning electron microscopy. The gold nanoclusters exhibit great electrocatalytic properties toward glucose with a wide linear range from 0.5 to 50 mM, with a limit of detection 218 μM, and sensitivity of 185.2 mA mM−1cm−2. Moreover, the modified microelectrodes display good reproducibility, stability, and selectivity in the presence of poisoning compounds. Due to the small dimensions of gold microelectrodes and a very small volume of the sample, the microelectrodes make a contribution to miniaturisation of the system.
