We described the use of a nanocomposite consisting of reduced graphene oxide and zinc tetraphenylporphyrin (RGO/Zn‐TPP) for electrochemical sensing of dopamine (DA). The surface of RGO was homogeneously functionalized with Zn‐TPP via non‐covalent π‐π interaction. The nanocomposite was characterized by scanning electron microscopy, UV‐Vis spectrometry, nuclear magnetic resonance spectroscopy and electrochemical impedance spectroscopy. The electroanalysis behavior of the nanocomposite was studied by cyclic voltammetry and amperometry. The excellent electrocatalytic activity is found for oxidation of DA, best at working voltage of 0.214 V (vs. Ag/AgCl) and linear response range of 0.04–238.8 μM. The sensitivity and detection limit were of 0.665 μA µM−1 cm−2 and 3 nM, respectrively. The electrode is well reproducible, stable, and represents a viable platform for the analysis of DA in DA injection, human serum and rat brain sample.

“…[17][18][19] Among different nanomaterials, the zinc oxide (ZnO) nanoparticles possess an important place due to their unique properties such as high specific surface area, optical transparency, high catalytic efficiency, strong adsorption ability, bio-compatibility, nontoxicity, chemical stability, ease of fabrication, fast electron transfer kinetics and electrochemical activities. 20,21 The use of ZnO nanoparticles in carbon paste electrodes is a promising approach to enhance the performance of electrochemical methods. 22,23 This study describes the development of a simple, reliable and sensitive square wave cathodic adsorptive stripping voltammetric method (SWCAdSV) based on ZnO nanoparticles modified carbon paste electrode (ZnO-NP-CPE) for the accurate and precise determination of MKST and its application in pharmaceutical preparations and biological fluids.…”

The electrochemical properties of montelukast sodium (MKST) at zinc oxide nanoparticles modified carbon paste electrode were investigated by cyclic voltammetry and square wave voltammetry. All studies were based on the irreversible and adsorption-controlled electrochemical reduction signal of montelukast sodium at about -0.7 vs. Ag/AgCl at pH 2.3 in methanol-Britton-Robinson buffer mixture. This adsorptive character of the molecule was used to develop a novel, validated, rapid, selective and simple square wave cathodic adsorptive stripping voltammeric method for the direct determination of montelukast sodium in pharmaceutical and biological fluids without time-consuming steps prior to drug assay. Peak current of electrochemical reduction of montelukast sodium was found to vary linearly with the concentration in the range from 1.0 × 10 -8 to 1.28 × 10 -6 mol L -1 . In this method, limit of detection was found to be 7.7 × 10 -9 mol L -1 . The method was applied to determine the content of MKST tablet and spiked human serum.
