The electrodeposition of reduced graphene oxide (rGO) film with preferred vertical orientation was fabricated on a glassy carbon electrode by using pulse potential method in a graphene oxide solution. The rGO film was applied in developing a high-sensitive electrochemical sensor for detection of levodopa (L-dopa). The new electrochemical sensor displayed a significant response to L-dopa because of its excellent electric conductivity and large specific surface area. Moreover, the determination of L-dopa on this modified electrode was not interfered by the coexistence of ascorbic acid (AA) and uric acid (UA). Under the selective conditions, the modified electrode showed a linear voltammetric response to L-dopa within a certain concentration ranging from [Formula: see text][Formula: see text] mol L[Formula: see text], with the detection limit of [Formula: see text] mol L[Formula: see text]. Besides, the modified electrode also exhibited an excellent selectivity, stability, reproducibility and repeatability.
