Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>This study describes the development, electrochemical characterization and utilization of 8, 9‐dihydroxy‐7‐methyl‐12<italic>H</italic>‐benzothiazolo [2, 3‐b]quinazolin‐12‐one (DMBQ)/ZnO nanoparticles (ZnO/Nps)‐carbon paste electrode (DMBQ/ZnO/NPs/CPE) as a modified sensor for the electrocatalytic determination of cysteine (Cys) in the presence of folic acid (FA). ZnO/NPs was synthesized and characterized by X‐ray diffraction (XRD) method. The prepared DMBQ/ZnO/NPs/CPE was developed as a highly sensitive voltammetric sensor for determination of Cys in the presence of FA in real samples. Square wave voltammetry (SWV) of Cys exhibited linear dynamic range with a detection limit (3<italic>σ</italic>) of 0.05 µmol/L.</p> </abstract>
