Carbon-based composite electrodes were heralded in biosensor applications as a new paradigm for an engineered electrode material because of their high electronic conductivity and useful mechanical properties. In particular, the exfoliated graphite can be an inexpensive alternative to carbon nanotubes for the fabrication of biosensor devices due to its high sensitivity and fast responsibility [1, 2]. Here we report about the exfoliated graphene/Nafion electrode (EGNE) for detection of glucose. The morphology of EGNE was investigated by SEM imaging. The electrochemical properties of EGNE were characterized by cyclic voltammetry and amperometric responses. The exfoliated graphene/Nafion hybrids have the potential use of an excellent electrode material in the biosensor application due to biocompatibility and excellent bioelectrocatalytic properties.
