The study of electrochemical behavior and determination of captopril, as an angiotensin-
converting enzyme inhibitor using a vinylferrocene modified multiwalled carbon nanotubes
paste electrode (VFMCNTPE) is reported. The cyclic voltammetric results indicate that the
VFMCNTPE system can remarkably enhance electrocatalytic activity toward the oxidation of
captopril in aqueous buffer solution pH 8.0. Under the best experimental conditions
selected, the calibration curve for captopril was linear in the concentration range from 0.2 ...
