Electrochemistry Behavior

Glassy carbon electrodes (GCEs) were modified by TiO2 and Ag/TiO2 heterostructured nanobelts, respectively. The corresponding electrodes were marked as TiO2/GCE and Ag/TiO2/GCE, respectively. The electrochemical properties of Ag/TiO2/GCE had good and stable electrochemical characteristics in phosphate buffer solution (PBS), and it can be applied to the trace detection of L-cysteine. When the concentration of L-cysteine is in 10-7 order of magnitude, it is more sensitive.

Pulse Voltammetry

Modified glassy carbon electrodes have been made by deposition of functionalised multiwalled carbon nanotubes (MWCNTs) followed by formation of poly(Nile blue) (PNB) films by electropolymerisation, using potential cycling in 0.1 M phosphate buffer solution (PBS) at pH 6.0. The electrochemical oxidation of carbidopa (CD) and benserazide (BS) on these MWCNTs/PNB-modified electrodes was investigated using cyclic and differential pulse voltammetry in 0.1 M PBS at different values of pH between 5.0 and 8.0; both CD and BS gave one diffusion-controlled irreversible oxidation peak in cyclic voltammetry. Analytical characterisation of CD and BS was carried out in 0.1 M PBS, pH 5.0. Peak currents in differential pulse voltammetry were linear over the concentration range of1×10−5to1×10−4 M for CD and4×10−6to4×10−5 M for BS. The repeatability, precision, and accuracy of the method were also investigated. Higher sensitivities and lower detection limits, of 1.17 μM for CD and 0.50 μM for BS, were obtained with this new modified electrode compared with previous studies reported in the literature.
