Abstract
The electrochemically functionalized multiwall carbon nanotubes/copper nanoparticles(fMWCNT/CuNPs) carbon paste electrode (fMWCNT/CuNPs-CPE) was successfully modifiedby silver nanoparticles (AgNPs) via electrocatalytic process. The formation of modified electrode (AgNPs/fMWCNT/Cu NP-CPE) was observed by Field Emission Scanning Electron Microscopy and X-ray diffraction techniques. The as-prepared electrodes were explored for thetrace recognition of calcium channel blocker drug amlodipine besylate (ADB) using cyclicvoltammetry and electrochemical impedance spectroscopy measurements. Kinetic parameterslike electron transfer coefficient (α), charge due to adsorption (Qads), surface coverage (Γ),charge transfer coefficient (Rct), and apparent electron-transfer rate constant (kapp) for the designed electrodes were evaluated. The nanoparticles based electrochemical sensor displayed highsensitivity, good selectivity and favorable catalytic ability for the oxidation of calcium channel blocker drug.
