Exfoliated graphite carbon paper-based flexible nonenzymatic glucose sensor

The continuous real-time monitoring of glucose is essential for patients suffering from diabetes. Therefore, low-cost and flexible glucose sensor is necessary, showing enhanced sensitivity and limit of detection. We report results of studies resulting in developing a nanostructured exfoliated graphite carbon paper (ExGCP) based efficient electrode for application to a nonenzymatic glucose sensor. This glucose sensor showed -sensitivity 5.93 mu A mM(-1) cm(-2) with a linear response in the 2-8 mM concentration range and-0.812 mM as the limit detection. The diffusion-controlled sensing reaction on ExGCP reduces electron transfer resistance with increasing glucose concentration, revealing ExGCP as an efficient and flexible electrode material for glucose sensing applications.
