Abstract
The electrochemical detection of neurotransmitters is an imperative application in the field of analytical chemistry. The recent development in the electrochemical sensors based on carbon electrodes is very important due to their sensitivity and simplicity. Using the carbon-based sensor for the electrochemical analysis of the neurotransmitters is a simple method. Furthermore, these above methods provide high sensitivity, are user-friendly, and are well-matched with the concept of green chemistry. In light of this matter, this review article is devoted to the voltammetric detection of neurotransmitters by using the carbon-based electrode. Here, we survey the accomplishments in the determination of numerous neurotransmitters with high selectivity and sensitivity provided using carbon-based electrodes. Attention is concentrated on the working electrode and its promising modification which is vital for further analysis of the neurotransmitters.
