“…Many researchers have already done various experimental investigations into the detection of dopamine, L-DOPA, and dopamine o-quinone [28][29][30]. There are a few papers on the dopamine adsorption on the CNT [31][32]. However, the literature does not compare dopamine with L-DOPA and dopamine oquinone for the adsorption on the CNT.…”

Detecting dopamine is of great biological importance because the molecule plays many roles in the human body. For instance, lack of dopamine release is the cause of Parkinson's disease. Although many researchers have carried out experiments on dopamine detection using carbon nanotubes (CNTs), there are only a few theoretical studies on this topic. We study the adsorption properties of dopamine and its derivatives, L-DOPA and dopamine o-quinone, adsorbed on a semiconducting (10, 0) CNT, using density functional theory calculations. Our computational simulations reveal that localized states originating from dopamine o-quinone appear in the bandgap of the (10, 0) CNT, but those originating from dopamine and L-DOPA do not appear in the gap. Therefore, dopamine oquinone is expected to be detectable using an external electric field but dopamine and L-DOPA should be difficult to detect.

“…This neurotransmitter plays some important roles in human and animals. It is synthesized by elimination of carboxylic group from the L-3,4-dihydroxyphenylalanine (L-DOPA) as its precursor [1]. One of the major functions of dopamine is in pleasure reward seeking behaviour [2].…”

In this work, a new modification strategy was reported to modify a glassy carbon electrode (GCE) based on ZnO/Al 2 O 3 nanocomposite. This modified electrode was designed in order to be used as a sensitive and selective sensor towards detection of trace amount of dopamine (DA). The effective parameters on the optimal performances of the electrode such as pH of the test solution and the applied scan rate during the electrochemical process were also studied. This sensor responded linearly towards detection of dopamine within a wide range of 5.0×10 −6 -7.0×10 −4 M with a low detection limit of 2.0×10 − 6 M (pH=7.0), under the optimum conditions. Moreover, the electrode functioned in the determination of dopamine in real samples was satisfactory.
