A sensitive electrochemical sensor was developed by cyclosporine and sodium dodecyl sulphate for the electrochemical detection of dopamine (DA). The modified Cyclosporine carbon paste electrode was further modified by immobilization of sodium dodecyl sulphate (SDS) as a surfactant. The Modified Cyclosporine/SDS carbon paste electrode showed an excellent electro catalytic activity towards the oxidation of dopamine. Cyclosporine/SDS modified carbon paste electrode enhanced the anodic peak current as compared to bare carbon paste electrode at pH 7.4, the electrochemical parameters like to scan rate and concentration of dopamine was investigated. Interference study at Cyclosporine/SDS modified carbon paste electrode reveals the excellent senility of electrode towards the dopamine, ascorbic acid and uric acid.
