Electrochemical deduction of levodopa by utilizing modified electrodes: A review

•Levodopa is an important compound.•The creation of analytical tools to determine levodopa is required.•This review is about electrochemical methods used for determination of levodopa. Parkinson's disease (PD) is a progressive and chronic movement impairment that is clinically distinguished by gait dysfunction, rigidity, tremor and bradykinesia. Parkinson's disease originators are unknown but this disease emerges when dopamine levels in the brain are decreased. For the purpose of appeasing the numerous symptoms of early stage PD, dopaminergic replacement therapy with a levodopa precursor can be beneficial. Thus, the creation of analytical tools to determine levodopa is required. Electrochemical mechanisms are typically used to detect levodopa. There have been recent advancements in using electrochemical detection for levodopa. In this study, the several uses of levodopa electrochemical sensors in areas such as pharmaceutical or clinical evaluation, with levodopa as a vital analyte are reviewed.
