“…4a. As can be seen, with the concentration of NaOH solution increased from 0.1 to 1.5 M, the anodic peak current and potential were respectively increased and decreased due to the promotion of the oxidation reaction rate of Ni(II)/Ni(III) and Cu(II)/Cu(III) by OH − [18,50]. Similarly, the peak current of glucose oxidation is also dependent on the NaOH concentration (Fig.…”

“…Although pristine CNTs are directly responsive to glucose and unaffected by the interfering species, a major limitation lies in the narrow linear range in glucose determination [32,33]. Therefore, CNTs are frequently used in conjunction with other catalytically active metals and alloys as well as metal oxides [2,8,18,25]. Recent developments in electrochemical sensor technology have also demonstrated that the electrocatalytic activity can be significantly increased by moving from bulk materials to nanosized structures due to the increase in the electrocatalytic active area and the promotion of electron transfer in glucose oxidation reactions [33,34].…”

In this study, copper/nickel (CuNi) particle decorated multiwalled carbon nanotubes (MWCNTs) have been fabricated for nonenzymatic glucose detection by the electrodeposition of CuNi particles on a glassy carbon electrode (GCE) modified with Nafion-functionalized MWCNTs (fMWCNTs). Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses reveal that CuNi particles were successfully deposited on the fMWCNTs/GCE. The as-synthesized CuNi/fMWCNT composite reveals the shape characteristics of dendrite with a Cu/Ni atomic ratio of around 88.1/11.9. The nonenzymatic glucose sensor based on CuNi/fMWCNT composite shows excellent electrocatalytic activity toward glucose oxidation with a high sensitivity (1470.2 μA cm −2 mM −1 ), a low detection limit (2.5 nM, signal/noise (S/N) ratio=3), and a wide linear range (0.1-5000 μM). Moreover, the sensor has been successfully used for the assay of glucose in human serum samples with good recovery, ranging from 95.6 to 100.1 %. These results indicate that CuNi/fMWCNT composite is an ideal candidate for novel nonenzymatic glucose sensor because of its high sensitivity, good selectivity, good stability, and low cost.

A nanocomposite consisting of reduced graphene oxide decorated with palladium-copper oxide nanoparticles (Pd-CuO/rGO) was synthesized by single-step chemical reduction. The morphology and crystal structure of the nanocomposite were characterized by field-emission scanning electron microscopy, high resolution transmission electron microscopy and X-ray diffraction analysis. A 3-electrode system was fabricated by screen printing technology and the PdCuO/rGO nanocomposite was dropcast on the carbon working electrode. The catalytic activity towards glucose in 0.2 M NaOH solutions was analyzed by linear sweep voltammetry and amperometry. The steady state current obtained at a constant potential of +0.6 V (vs. Ag/AgCl) showed the modified electrode to possess a wide analytical range (6 μM to 22 mM), a rather low limit of detection (30 nM), excellent sensitivity (3355 μA mM −1 cm −2 ) and good selectivity over commonly interfering species and other sugars including fructose, sucrose and lactose. The sensor was successfully employed to the determination of glucose in blood serum.

“…For example, CuO nanocubes were deposited on a graphene film by the EPD process, under the optimized conditions, a linear at a positive potential (i.e. 0.55 V) was achieved [100]. In order to improve the performance of CuO-modified graphene paper as non-enzymatic sensor, CuO-functionalized S-doped graphene was successfully synthesized through a facile microwave-assisted approach.…”

Graphene paper as a new form of graphene-supported nanomaterials has received worldwide attention since its first report in 2007. Due to their high flexibility, lightweight and good electrical conductivity, graphene papers have demonstrated the promising potential for crucial applications in electrochemical sensors and energy technologies among others. In this chapter, we present some examples to overview recent advances in the research and development of two-dimensional (2D) graphene papers as new materials for electrochemical sensors. The chapter covers the design, fabrication, functionalization and application evaluations of graphene papers. We first summarize the mainstream methods for fabrication of graphene papers/membranes, with the focus on chemical vapour deposition techniques and solution-processing assembly approaches. A large portion of this chapter is then devoted to the highlights of specific functionalization of graphene papers with polymer and nanoscale functional building blocks for electrochemical-sensing purposes. In terms of electrochemical-sensing applications, the emphasis is on enzyme-graphene and nanoparticle-graphene paper-based systems for the detection of glucose. We finally conclude this chapter with brief remarks and outlook.
