Determination of Glucose in Human Serum Using Background Subtraction of Cyclic Voltammetry of a Low Oxidation Peak at NiO Based Electrode

Abstract

In this study, the background subtraction of cyclic voltammetry of a low oxidation peak at NiO based electrode is employed for the determination of glucose in human serum in 0.1 M NaOH medium with 2 linear ranges of 10 to 100 μM and 100 to 2000 μM with a detection limit of 2 μM and sensitivities of 2942.2 and 754.2 μAcm-2mM-1, respectively. As a result, determining the glucose concentration in the real sample shows that this type of NiO-based sensor can be used in practice and approach to accurately determining the glucose concentration in human serum.
