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.

Development, Characterization and Application of a Carbon‐Based Nanomaterial Composite as an Electrochemical Sensor for Monitoring Natural Antioxidant (Gallic Acid) in Beverages

Gallic acid (GA) is an important organic acid, found in many natural plants and in food beverages. Here in, we have developed a chemical sensor for the monitoring of GA in wine, green tea and fruit juices. The oxidation of GA was found to be an irreversible process and the corresponding mechanism was proposed. The effect of pH on the oxidation behavior was studied and pH‐6.0 was selected as an optimum pH. Based on the scan rate results a linear relation was observed between the square root of scan rate and peak currents for GA, confirming the oxidation of GA as a diffusion controlled process. The kinetic parameters such as diffusion coefficient, heterogeneous rate constant and charge transfer coefficient values were determined. The limit of detection (LOD) and quantification (LOQ) values were calculated as 4.39 × 10‐7 M and 1.46 × 10‐6 M. The repeatability, reproducibility and stability of the developed sensor were examined and the results confirmed that the developed sensor was in superior in condition. Finally, the practical application of the developed sensor was scrutinized for the quantitative estimation of GA in wine, green tea and fruit juices.

A new highly sensitive and selective electrochemical levofloxacin sensor based on co‐polymer‐carbon nanotube composite electrode was developed. Taurine and Glutathione were electrochemically co‐polymerized on multiwalled carbon nanotubes modified glassy carbon electrode (Poly(TAU‐GSH)/CNT/GCE) and used as a levofloxacin sensor in pH 6 phosphate buffer solution. The new composite electrode surfaces were characterized by scanning electron microscopy, atomic force microscopy and electrochemical impedance spectroscopy. Under the optimized conditions, two linear segments were obtained for increasing LEV concentrations between 20 nmol L−1‐1 μmol L−1 and 1.5 μmol L−1‐55 μmol L−1 LEV with a detection limit of 9 nmol L−1 using amperometry. Poly(TAU‐GSH)/CNT/GCE exhibited high sensitivity, selectivity with good stability. The new sensor was employed for real samples of LEV tablets and urine. Promising results were obtained with good accuracy which were also in accordance with LC‐MS/MS analysis.
