The electrochemical behaviour of levodopa (LD) has been investigated at multiwalled carbon nanotube (MWCNT) and poly(Nile blue‐A) (PNB) modified glassy carbon electrodes (GCE). MWCNT/PNB modified electrodes were prepared by NB potential cycling electropolymerisation in 0.1 M phosphate buffer solution (PB), pH 6.0, followed by MWCNT deposition, and PNB/MWCNT/GCE by coating in the inverse order. The oxidation behaviour of LD was investigated in 0.1 M PB at pH values between 5.0 and 8.0. Quantitative determination of LD by differential pulse and square wave voltammetry was carried out in 0.1 M PB at pH 6.0. Analytical parameters were compared with the literature.
