“…Although these methods are generally quite sensitive and accurate, they are often costly, technically complex, time-consuming, and do not allow high throughput analysis. Recently, electrochemical methods, especially electrochemical RIF (rifampicin) sensors [10][11][12][13][14][15][16][17], have gained attention due to their outstanding merits, which includes the simplicity of the sample preparation, low cost of instrumentation, easy miniaturization, high sensitivity and selectivity. In particular, sensors based on metal oxide nanomaterials are well known for their excellent electrical, optical, thermal and catalytic properties, and large surface-to-volume ratio [18,19].…”

Herein, a “nanonetwork” modified electrode was fabricated based on multiwalled carbon nanotubes and CeO2 nanorods. Scanning electron microscopy, X-ray powder diffraction and zeta potential were employed to characterize this electrode. Multiwalled carbon nanotubes negatively charged and CeO2 nanorods positively charged form “nanonetwork” via electrostatic interaction. The performance of the CeO2 nanorods-based electrode remarkably improved due to the introduction of multiwalled carbon nanotubes. The detection of rifampicin (RIF) was used as a model system to probe this novel electrode. The results showed a significant electrocatalytic activity for the redox reaction of RIF. Differential pulse voltammetry was used to detect rifampicin, the reduction peak current of rifampicin linear with the logarithm of their concentrations in the range of 1.0 × 10−13–1.0 × 10−6 mol/L, The linear equation is ip = 6.72 + 0. 46lgc, the detect limit is 3.4 × 10−14 mol/L (S/N = 3). Additionally, the modified electrode exhibits enduring stability, excellent reproducibility, and high selectivity. This strategy can be successfully used to detect trace rifampicin in samples with satisfactory results.

“…Nowadays, modification of the electrode surfaces with nanomaterials is method of choice for improving sensitivity, selectivity and precision. Carbon allotropes , conducting polymers , metal oxides , metal nanoparticles and their combinations are the most known modifiers for the achieving not only for highest sensitivity but also, satisfactory selectivity for trace analysis. Since their discovery in 1991 by Iijima, carbon nanotubes (CNTs) are very versatile materials because of their unique characteristics such as; chemical and thermal stability, conductivity, high surface area.…”

Copper oxide decorated multi‐walled carbon nanotube (MWCNT) modified glassy carbon electrode (GCE) was prepared for determination of isoniazid (INZ) in various matrices. The electrochemical behavior of INZ was tested with the aid of Cyclic Voltammetry (CV) and quantitative experiments were performed by using Linear Sweep Voltammetry (LSV). Morphological and structural characterization of the modified electrode was performed by utilizing Scanning Electron Microscopy (SEM), X‐Ray Photoelectron Spectroscopy (XPS) while electrochemical characterization was performed by using CV and Electrochemical Impedance spectroscopy (EIS). The proposed sensor exhibited well defined anodic peak at 0.30 V for INZ at pH 6.0 medium. Under the optimum conditions, a linear relation between INZ concentration and peak current was observed in the range of 2.0×10−7 to 5.0×10−5 M. Limit of detection was calculated as 1.0×10−8 M and repeatability and accuracy was found as 5.60 % and 91.0 % for 5.0 10−7 M INZ by using 3 successive measurement, respectively. Then, the analytic performance of the electrode developed was tested by analyzing commercial tablets, artificial human serum and urine samples. The results indicated that satisfactory recoveries was observed for all issue.

“…The films were used as precursors to produce NiHCFe through cyclic voltammetry in K 3 [Fe(CN) 6 ] acid aqueous solution, based on a heterogeneous electrochemical reaction similar to that previously described for PB and other PBAs, i.e., between the metallic nickel in the nanocomposite-based electrodes and [Fe(CN) 6 ] 3À anions in the electrolyte aqueous solution. 50 All the cyclic voltammograms exhibited the characteristic [Fe(CN) 6 ] 4À /[Fe(CN) 6 ] 3À redox pair at B0.280/0.190 V. In addition, the first cyclic voltammogram of the rGO/Ni thin film exhibits an intense anodic peak at B1.0 V attributed to the oxidation of Ni to Ni 2+ and a cathodic peak at B0.4 V probably due to the initial formation of NiHCFe (Fig. 2A).…”
