| Popis: | This paper presents new two electrochemical sensors based on Ag nanoparticles (AgNPs) decorated anchored type ligands, those were prepared based on synthesizing of two amine compounds bounded to silica support, to detect glucose. These compounds were characterized using transmission electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscopy. TEM monitored AgNPs around 10 nm in size. These electrocatalytic properties of the modified carbon paste electrodes (CPEs) were investigated by electrochemical techniques including cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and hydrodynamic amperometry. According to amperometric studies, the better glucose sensor represented the detection range of 28.6 µmol/L to 9.80 mmol/L glucose, with detection limit of 5.5 µmol/L and sensitivity of 540.7 µA/mM. In this work, three human blood serums were employed as real samples with satisfactory results. |
