Three-dimensional (3D) copper–cobalt (Cu–Co)/reduced graphene oxide (rGO) hierarchical architectures are electrochemically deposited over a pencil graphite electrode (PGE), and the modified PGE is directly exploited as binder-free disposable for high performance nonenzymatic glucose sensors. The morphological features substantiate that Cu–Co nanostructures display 3D, open, porous, interconnected network architecture, in which rGO layers tightly pinned among nanofeelers. Owing to benefits of dendrite optimized composition, Cu–Co/rGO/PGE demonstrates better oxidation behavior under alkaline conditions. Being sensor, excellent gluose detection properties with considerable chloride poisoning resistance. analytical comprehends its application human serum samples. Thus, this report paves constructive opportunities development disposable, environmentally benign, binder-free, cost-efficient, scalable 3D electrodes, may be beneficial economically viable sensor devices.
