This review is presenting the design and performance of some electrochemical sensors used for the determination of L‐dopa in real samples as reported in a series of relevant scientific papers published in the past 5 years. L‐dopa was intensively studied using electrochemical sensors with applications in the biomedical field, pharmaceutical field and food industry. The determination of L‐dopa is of great importance, due to the fact that it can cross the blood brain barrier (which dopamine can't) and then can be converted to dopamine. Thus, it can be used in treating some disease, such as Parkinson's. Because fast detective methods for L‐dopa determination are required, this paper focused on four types of electrochemical sensors, such as modified carbon paste electrodes, modified glassy carbon electrodes, modified screen‐printed electrodes and modified indium tin oxide electrodes. Each has its advantages and disadvantages and the appropriate sensor should be used depending on the type of application.
