“…Insufficient DA concentration due to the loss of DA-producing cells may lead to a disease called Parkinson's disease [2] in which a person loses the ability to execute smooth and controlled movements [3][4][5]. DA can be supplied as a medication, however its excess dosage may act on the sympathetic nervous system causing increased heart rate and blood pressure.…”

“…The malfunction of the dopamine system results in several brain diseases, such as attention deficit hyperactivity disorder, restless legs syndrome, schizophrenia, Parkinson's, and Alzheimer's disease. [11][12][13][14] The DA concentration is quite low in the nerve cell. In the extracellular fluid of the central nervous system and cerebrospinal fluid, DA concentration is 100 nM 15 and also, depending on location, the concentration of DA ranges broadly from 1.0×10 −7 M to 1.0×10 −3 M. 16 Several methods have been implemented to detect DA, such as electrogenerated chemiluminescence, colorimetry, capillary electrophoresis, fluorescence spectrometry, and high-performance liquid chromatography.…”

Dopamine is a neurotransmitter of the catecholamine family and has many important roles, especially in human brain. Several diseases of the nervous system, such as Parkinson’s disease, attention deficit hyperactivity disorder, restless legs syndrome, are believed to be related to deficiency of dopamine. Several studies have been performed to detect dopamine by using electrochemical analysis. In this study, quantum dots (QDs) were used as sensing media for the detection of dopamine. The surface of the QDs was modified with l -cysteine by coupling reaction to increase the selectivity of dopamine. The fluorescence of cysteine-capped indium phosphide/zinc sulfide QDs was quenched by dopamine with various concentrations in the presence of ascorbic acid. This method shows good selectivity for dopamine detection, and the detection limit was 5 nM.

In this study, a rapid and sensitive method is described for the catecholamines detection in rat brain. CE with LIF detection for the determination of FITC derivatized catecholamines (dopamine, epinephrine, and norepinephrine) was demonstrated. Conventional water bath and microwave-assisted derivatization methods were employed and a significant reduction in the derivatization time from 2 h for the conventional water bath at room temperature (ca. 25°C) to 2 min for the microwave-assisted derivatization was achieved. Online sample concentration of field-amplified sample stacking (FASS) method was employed to achieve higher sensitivities (the detection limits obtained in the normal injection mode ranged from 2.6 to 4.5 ng L⁻¹ and in the FASS mode ranged from 22 to 34 pg L⁻¹). Furthermore, this microwave-assisted derivatization CE-LIF method successfully determined catecholamines in rat brain with as low as 100 ng L⁻¹ (FASS mode) to 10 μg L⁻¹ (normal injection mode). This CE-LIF method provided better detection ability when compared to the best reports on catecholamines analyses.
