Graphical abstractSchematic representation showing the formation of cobalt phthalocyanine nanorods (nanoCoPc) on graphene (Gr) and schematic illustration of glucose sensing on the surface of ®Nafion/GOD/nanoCoPc-Gr/GCEThe nanocomposite of nanoCoPc-Gr was formed according to two main processes. The large conjugated system of Gr caused the formation of CoPc macrocycles on its surface via π-π stacking interactions. Then CoPc molecules aggregated to form nanorods through the same π-π accumulation effect, and the final nanoCoPc-Gr was obtained.The mechanism of glucose sensors is based on monitoring of hydrogen peroxide (H2O2). Glucose oxidase (GOD) can oxidize β-D-glucose into gluconic acid, accompanied by the consumption of O2 and the liberation of H2O2. Subsequently, H2O2 diffuses into the layer of nanoCoPc-Gr, and gets oxidized. The nanoCoPc-Gr acts as a catalyst to reduce the oxidation overpotential of H2O2 on the electrode. The response of H2O2 is used to indirectly evaluate the glucose concentration in the solution.
