A novel electrochemical sensor for sensitive detection of methyldopa at physiological pH was developed by the bulk modification of carbon paste electrode (CPE) with graphene oxide nanosheets and 3‐(4′‐amino‐3′‐hydroxy‐biphenyl‐4‐yl)‐acrylic acid (3,′AA). Applying square wave voltammetry (SWV), in phosphate buffer solution (PBS) of pH 7.0, the oxidation current increased linearly with two concentration...
A modified glassy carbon electrode has been constructed using a 1-benzyl-4-ferrocenyl-1H-[1,2,3]-triazole along with multiwalled carbon nanotubes. The electrochemical behaviour of modified electrode has been investigated by cyclic voltammetry. Electrocatalytic activity of the modified electrode was investigated for the oxidation of hydroxylamine in 0.1 M phosphate-buffered solution of pH 8. The modified...
A carbon paste electrode modified with carbon nanotubes and ferrocene was fabricated. An electrochemical study of the modified electrode and an investigation into its efficiency for the electrocatalytic oxidation of benserazide, uric acid and folic acid were undertaken. The electrode was also used to study the electrocatalytic oxidation of benserazide using cyclic voltammetry, chronoamperometry, and...
