“…Copper-and copper oxide-based materials were of great interest for the electro-oxidation of glucose for a long time [8,9]. Recently, there is a great amount of interest on copper and copper oxide nanomaterials for the non-enzymatic detection of glucose [10][11][12].…”

We have developed a non-enzymatic glucose sensor by using a composite prepared from copper nanoparticles (CuNPs) and graphene which can be prepared by simple 1-step electrochemical reduction using graphene oxide (GO) and copper ion as the starting materials. The GO is electrochemically reduced to graphene at a voltage of −1.5 V, and this is accompanied by the simultaneous formation of CuNPs on the surface of the graphene. This novel nanocomposite combines the advantages of graphene and of CuNPs and displays good electrocatalytic activity toward glucose in alkaline media. The performance of the respective glucose electrode was evaluated by amperometric experiments and revealed a fast response (<2 s), a low detection limit (200 nM), and high sensitivity (607 μA mM −1 ). The sensor also exhibits good reproducibility and very good specificity for glucose over ascorbic acid, dopamine, uric acid, fructose, lactose and sucrose.

“…have been widely employed to improve the analytical performance of the first-generation glucose biosensors [40]. Recently, electrospun metal oxide nanofibers and noble metal nanofibers have attracted increasing attention [41][42][43][44] because nanofibers can form highly porous 3-D networks which have unique advantages in immobilizing enzyme and retaining its bioactivity due to their high surface to volume ratio, the favorable microenviroment for enzyme immobilization, the minimized diffusion resistance for analytes, and numerous electron transfer channels for enhanced electron transfer [45].…”

The highly porous Mn 2 O 3 -Ag nanofibers were fabricated by a facile two-step procedure (electrospinning and calcination). The structure and composition of the Mn 2 O 3 -Ag nanofibers were characterized by SEM, TEM, XRD, EDX and SAED. The as-prepared Mn 2 O 3 -Ag nanofibers were then employed as the immobilization matrix for glucose oxidase (GOD) to construct an amperometric glucose biosensor. The biosensor shows fast response to glucose, high sensitivity (40.60 mA mM À1 cm À2 ), low detection limit (1.73 mM at S/N = 3), low K m,app value and excellent selectivity. These results indicate that the novel Mn 2 O 3 -Ag nanfibers-GOD composite has great potential application in oxygen-reduction based glucose biosensing.

“…Thus, it is important to develop a sensing tool that detects accurately the level of glucose both in vivo and in vitro. 27 In this context, economical electrooxidation catalysts with relatively simple preparation method, high sensitivity, fast response, good stability, and reproducibility have been thoroughly investigated. 22 Metal-or metal oxide-based nanostructures in sensor application are gaining wide popularity due to their high reactivity at the surface, catalytic efficiency, fast electron communications, and retention of the catalytic property for a long period of time.…”

Moreover, these nanostructures can significantly reduce the sensor size, thus reducing the cost factor; in addition, they can be used in continuous monitoring of urine, blood, or serum samples.…”

“…Recently, CuO nanostructures have been investigated for biosensing applications because of their enhanced catalytic effect and resistance to surface poisoning. 28 CuO nanoparticles, 29 nanoplatelets, 30 nanowires, 27 nanoflowers, and nanorods 10 have been applied for glucose detection with good sensitivity. Most of the synthetic protocols for the formation of these attractive nanostructures are tedious and expensive.…”

In this work, three different spherulitic nanostructures Cu–CuO A , Cu–CuO B , and Cu–CuO C were synthesized in water-in-oil microemulsions by varying the surfactant concentration (30 mM, 40 mM, and 50 mM, respectively). The structural and morphological characteristics of the Cu–CuO nanostructures were investigated by ultraviolet–visible (UV–vis) spectroscopy, X-ray diffraction, scanning electron microscopy, and high-resolution transmission electron microscopy techniques. The synthesized nanostructures were deposited on multiwalled carbon nanotube (MWCNT)-modified indium tin oxide (ITO) electrodes to fabricate a nonenzymatic highly sensitive amperometric glucose sensor. The performance of the ITO/MWCNT/Cu–CuO electrodes in the glucose assay was examined by cyclic voltammetry and chronoamperometric studies. The sensitivity of the sensor varied with the spherulite type; Cu–CuO A , Cu–CuO B , and Cu–CuO C exhibited a sensitivity of 1,229, 3,012, and 3,642 µA mM −1 ·cm −2 , respectively. Moreover, the linear range is dependent on the structure types: 0.023–0.29 mM, 0.07–0.8 mM, and 0.023–0.34 mM for Cu–CuO A , Cu–CuO B , and Cu–CuO C , respectively. An excellent response time of 3 seconds and a low detection limit of 2 µM were observed for Cu–CuO B at an applied potential of +0.34 V. In addition, this electrode was found to be resistant to interference by common interfering agents such as urea, cystamine, L-ascorbic acid, and creatinine. The high performance of the Cu–CuO spherulites with nanowire-to-nanorod outgrowths was primarily due to the high surface area and stability, and good three-dimensional structure. Furthermore, the ITO/MWCNT/Cu–CuO B electrode applied to real urine and serum sample showed satisfactory performance.
