“…Nafion ® consists of a tetrafluoroethylene main chain with perfluoroether side chains terminated with a sulfonic acid group. Several studies in the literature [23,24,25] demonstrate the increase the selectivity of Nafion ® -coated sensors in the determination of catecholamines in biological fluids minimizing the effect of some endogenous interferences (ascorbic acid and uric acid).…”

Neurotransmitters are endogenous chemical messengers which play an important role in many of the brain functions, abnormal levels being correlated with physical, psychotic and neurodegenerative diseases such as Alzheimer's, Parkinson's, and Huntington's disease. Therefore, their sensitive and robust detection is of great clinical significance. Electrochemical methods have been intensively used in the last decades for neurotransmitter detection, outclassing more complicated analytical techniques such as conventional spectrophotometry, chromatography, fluorescence, flow injection, and capillary electrophoresis. In this manuscript, the most successful and promising electrochemical enzyme-free and enzymatic sensors for neurotransmitter detection are reviewed. Focusing on the activity of worldwide researchers mainly during the last ten years (2010–2019), without pretending to be exhaustive, we present an overview of the progress made in sensing strategies during this time. Particular emphasis is placed on nanostructured-based sensors, which show a substantial improvement of the analytical performances. This review also examines the progress made in biosensors for neurotransmitter measurements in vitro, in vivo and ex vivo.

“…(2014) in the same manner. [ 121 ] Simultaneous determination of DA, UA, and Try using CV was achieved with the highest oxidation peak current and peak separation at FTO/fMWCNTs‐RuRe‐NF when compared to the result at other electrodes. In a CV experiment at the fMWCNTs‐RuRe‐NF modified electrode for DA, UA, and Try determination, LOD of 0.15, 0.14, and 0.14 µM, respectively, were obtained.…”

Neurotransmitters (NTs) are chemical compounds that play an important physiological role in the functioning of central nervous, renal, hormonal, and cardiovascular systems. Their function is to regulate neural interactions by reducing the permeability of gap junctions between adjacent neurons of the same type. The abnormal level may lead to diseases, such as Parkinson's disease, Huntington's disease, Alzheimer's diseases, and other neurological diseases. The devastating health hazards associated with the abnormal presence of NTs in biological systems coupled with the demerits of most modern detection methods necessitates the continuous development of novel electrochemical sensors. Carbon nanotube (CNT)-based sensors, as a result of the large surface area, biocompatibility, and chemical stability supplied by CNTs, have proven to offer massive sensitivity and low limit of detection (LOD). Its significance in sensors applications toward the detection of different group of compounds cannot be overemphasized. There are several review articles on NTs and their determination using different chemically modified electrodes and sensor platform. However, this review highlights the significance of notable NTs and the progress made in the last decade in the design of CNT-based sensors for the detection of common NTs.

“…In addition, conventional electrodes have a pronounced fouling effect, which can result in poor selectivity and reproducibility. To overcome these obstacles, so far, various materials have been used to modify conventional electrodes for the simultaneous detection of AA, DA, and UA 15 – 17 ; of UA and Trp 18 ; of Trp and , of DA, UA and Trp 19 , 20 ; of AA, DA, UA, and Trp 21 , 22 ; and of AA, DA, UA, and . Unfortunately, there have been no reports that the simultaneous determination of all five.…”

The development of electrochemical biosensors for the simultaneous detection of ascorbic acid (AA), dopamine (DA), uric acid (UA), tryptophan (Trp), and nitrite () in human serum is reported in this work. Free-standing graphene nanosheets were fabricated on Ta wire using the chemical vapor deposition (CVD) method. CVD graphene, which here served as a sensing platform, provided a highly sensitive and selective option, with detection limits of AA, DA, UA, Trp, and of 1.58, 0.06, 0.09, 0.10, and 6.45 μM (S/N = 3), respectively. The high selectivity of the electrode is here explained by a relationship between the bandgap energy of analyte and the Fermi level of graphene. The high sensitivity in the oxidation current was determined by analyzing the influence of the high surface area and chemical structure of free-standing graphene nanosheets on analyte adsorption capacity. This finding strongly indicates that the CVD graphene electrode can be used as a biosensor to detect five analytes in human serum.
