Electrochemical Detection of Adrenaline Using Nafion–Trimethylsilyl and Nafion–Trimethylsilyl–Ru2+-Complex Modified Electrodes

Year: 2025

Type: article

Abstract: The properties of Naf-TMS (Nafion-trimethylsilyl) and Naf-TMS/Ru-complex modified electrodes are reported for the electrochemical oxidation reaction of adrenaline (AD). The structure of Naf-TMS allows for hydrophobic and hydrophilic interactions with [Ru(bpy)3]2+ and [Ru(phen)3]2+ complexes in order to form stable Naf-TMS/Ru-complex polymer composites. Electrodes modified with this composite polymer, showed a faster electron transfer and greatly improved kinetic values for the redox reaction of AD in standard solutions, when compared to bare and Naf-TMS modified electrodes. A pH dependence of the electroanalytical parameters indicates that electron transfer reaction occurs in tandem with proton transfer, this allows to find the best analytical conditions for the detection of AD with Naf-TMS/Ru-complex modified electrodes.
