Fabrication of a New Electrochemical Sensor Based on Bimetal Oxide for the Detection of Furazolidone in Biological Samples

Abstract

This study utilized a simple hydrothermal method to synthesize nickel molybdenum oxide (NMO) for the detection of furazolidone (FZE). Our synthesized NMO was characterized by X-Ray diffraction (XRD), X-Ray photoelectron spectroscopy (XPS), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), field emission scanning electron spectroscopy (FE-SEM), and energy dispersive X-Ray spectroscopy (EDX). The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were used to detect the FZE. Under optimized conditions, the obtained results showed that the NMO had an excellent electrocatalytic property towards FZE. As a result, NMO/GCE showed a good linear range of 0.001–1765 µM, an excellent detection limit (LOD) of 0.02 µM, and sensitivity of 0.2042 µA µM−1 cm−2.

A Paper-Based Electrochemical Sensor Based on PtNP/COFTFPB−DHzDS@rGO for Sensitive Detection of Furazolidone

“…The CVs of PtNP/COF TFPB−DHzDS @rGO/GCE in a 0.1 M N 2 -statured phosphate-buffered solution (pH = 7.0) with 10 µM furazolidone showed an obvious reduction of furazolidone and an indistinct oxidation peak. According to a previous report [ 36 ], the redox mechanism is speculated to be that the nitrogroup contained in the structure of furazolidone is reduced under the synergistic catalysis of Pt and rGO. With the increase in the scanning rate, the peak current density of furazolidone increased ( Figure 3 c), and a good linear relationship was presented ( Figure 3 d), indicating that the reaction process was a typical surface control process [ 37 , 38 ].…”

“…Also, binary metal oxides are desirable to create active electrode materials due to their electrical conductivity and possible oxidation state. 23 Among the MO NPs, manganese oxide possesses abundant physiochemical characteristics such as large surface area, high stability, diverse oxidation states, mixed valence, and reversible reduction property (Mn 4+ 4 Mn 3+ ), which inuence its electrocatalytic performance. 24 Also, MnO has been combined with different components to overcome its intrinsic low conductivity.…”
