Therefore, monitoring and determining the amount of glucose in the blood is of great importance for the diagnosis of diabetes. In this study, a self-powered glucose determination was developed using glucose/air enzymatic fuel cell (EnFC) on a single chip. The anode of the EnFC is prepared by immobilizing glucose oxidase enzyme on ferrocene-nafion containing multi-walled carbon nanotube modified electrodes; the cathode, on the other hand, was prepared by immobilizing bilirubin oxidase enzyme on acid-treated single-walled carbon nanotube modified electrodes. The prepared anode and cathode were electrochemically characterized using glucose and oxygen substrates respectively. EnFC prepared on a single chip showed a linear response in the range of 0-3 mM glucose concentrations, achieving 32 mV/mM sensitivity and a response time of 30 seconds. <br /> </p>}, number={2}, publisher={Bilecik Seyh Edebali University}, organization={Bilecik Şeyh Edebali Üniversitesi}
