“…Glucose concentration higher than 12 mM did not yield a current in the linear region. The linear response obtained in the range of 1 to 12 mM is an improvement related to 0.05-100 μM reported recently for comparable systems [33][34][35]. In the present system, presence of oxygen did not influence the rate of the reaction and hence the catalytic current is obtained.…”

Electrochemical detection of glucose was performed on carbon nanofibers containing an osmium based redox polymer and using glucose oxidase enzyme. Redox polymer assembled on the nanofibers provided a more stable support that preserved enzyme activity and promoted the electrical communication to the glassy carbon electrode. The morphologies, structures, and electrochemical behavior of the redox polymer modified nanofibers were characterized by scanning electron microscope, energy dispersive spectrometer and voltammetry. The glucose oxidase showed excellent communication with redox polymer as observed with the increased activity toward glucose. Both cyclic voltammetry and amperometry showed a linear response with glucose concentration. The linear range for glucose determination was from 1 to 12 mM with a relatively high sensitivity of 0.20±0.01 μA mM −1 for glucose oxidase in carbon nanofibers and 0.10±0.01 μA mM −1 without carbon nanofibers. The apparent Michaelis-Menten constant (Km) for glucose oxidase with carbon nanofibers was 0.99 mM. On the other hand, the Km value for the glucose oxidase without the nanofibers was 4.90 mM.

“…Using microwave synthesis method, active materials with unique structures can be supported on graphene within short reaction time. For instance, cobalt phthalocyanine nanorods were adsorbed onto graphene (CoPc‐Gr) (Figure B) by a one‐step microwave method at 120 °C for 20 min . Nanoneedle‐like CuO grown from the center of the rambutan were supported on graphene oxide at 130 °C for 10 min in a microwave oven (Figure C) .…”

With the increasing demand for highly sensitive and selective glucose sensors in industrial, clinical and pharmaceutical sectors, sensing materials for glucose detection have attracted much attention worldwide. Due to the large surface area, fascinating physical and electrochemical properties, graphene‐based materials have been widely used as a unique class of promising electrode materials in electrochemical sensing applications, with the continuously growing academic and technological developments. In this review, we summarize the different preparation strategies for the synthesis of graphene‐based materials and the application in electrochemical detection of glucose, including enzymatic and nonenzymatic glucose sensors.

“…The decoration of macro or microelectrodes with nanomaterials is a common strategy for improving sensor performance with carbon nanotubes, 46 nanorods, 47 and gold nanoparticles 48 all finding applications for glucose sensing. The incorporation of these nanomaterials increases the roughness and surface area of larger electrodes, while they may also exhibit favorable electrocatalytic properties toward electroactive compounds.…”
