ABSTRACT
A new simple novel electrochemical sensing platform based onelectrodeposition ofnano zinc
oxide ontomultiwalled carbon nanotubes modified glassy carbon electrode was constructed. The
modified electrode was characterized by cyclic voltammetry and electrochemical impedance in a
redox probe.The electrode surface area after modification was 0.15 cm2, which was twice large
that of a bare glassy carbon electrode. The new fabricated sensor was applied for individual and
simultaneous determination of caffeine and acetaminophen. The limit of detection (LOD)for
individual determination was 3.69 × 10 M for acetaminophen and 3.52 × 10 M for
caffeine.The electrode showed good reproducibility, sensitivity and stability for detection of both
acetaminophen and caffeine. A good recovery level obtained for real samples suggests practical
utility of the ZnO/MWCNT/GCE as an effective sensor for simultaneous determination of
acetaminophen and caffeine.
