dc.description.abstract | Insulin is a key regulator in glucose homeostasis and its deficiency or alternations in the human body causes various types of diabetic disorders. In this paper, we present the development of a reduced graphene oxide (rGO) modified interdigitated chain electrode (ICE) for direct capacitive detection of insulin. The impedance properties of rGO-ICE were characterized by equivalent circuit modeling. After an electrochemical deposition of rGO on ICE, the electrode was modified with self-assembled monolayers and insulin antibodies in order to achieve insulin binding reactions. The impedance spectra and capacitances were measured with respect to the concentrations of insulin and the capacitance change (C) was analyzed to quantify insulin concentration. The antibody immobilized electrode showed an increment of C according to the insulin concentration in human serum ranging from 1 ng/mL to 10 mu g/mL. The proposed sensor is feasible for label-free and real-time measuring of the biomarker and for point-of-care diagnosis. | - |
