Abstract
The continuous real-time monitoring of glucose is essential for patients suffering from diabetes. Therefore, the 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 as 5.93 µA mM−1 cm−2 with a linear response in the 2–8 mM concentration range and ∼0.812 mM as the limit of 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.
