摘要：

In this study, Orobanche aegyptiaca Pers., which is an important holoparasite plant, was used for green synthesis of reduced graphene oxide silver nanocomposites (rGO-AgNCs). The obtained rGO-AgNCs were characterizated using UV-Vis spectroscopy, Fourier transformation infrared spectroscopy (FT-IR), X-Ray diffractiometer (XRD), Scanning electron microscope (SEM), Transmission electron microscope (TEM), and X-Ray photoelectron spectroscopy (XPS). The synthesized rGO-AgNCs structure were used to modify carbon paste electrode (rGO-AgNCs@CPE) for electrochemical determination of metronidazole (MNZ). It was observed that the obtained rGO-AgNCs@CPE showed higher sensitivity in MNZ determination than the unmodified CPE, and DPV measurements showed a low detection limit of 0.039 mu M over a linear concentration range of 5-300 mu M. Real sample analysis of the proposed sensor shows that it responds well in MNZ analysis of human urine.
