In recent years, nanomaterials have been investigated for various sensing applications because of their structural advantages. However, electrochemical sensors based on nanoparticles are still limited due to the inherent zero-dimensional structure. In this research, a novel hybrid structure based on nanowire array coated with nanoparticles has been developed. The vertical Pt nanowire array was prepared by template electrodeposition on an Ag substrate, followed by an electroless plating to deposit Au nanoparticles onto the nanowires. Glucose oxidase enzyme (GOD) was then immobilized on the nanoparticle surface with crosslinking agents. Various characterizations were performed to investigate the structure, morphology, and electrochemical performance of the hybrid sensor. Due to the extremely high density of GOD immobilized and the absence of Nafion, higher sensitivity, better repeatability and longer durability was achieved for the glucose sensor. This novel biosensor based on 3D hybrid structure provides a promising platform for cheaper and quicker biomolecular detection.
