“…The normal human 5-HT level reported by the US Department of Health, Human Services and National Institutes of Health (NIH) is 0.25-0.74 mM [5]. On the other hand, extremely high levels of 5-HT can cause toxicity and potentially fatal effects such as serotonin syndrome [4,6], obsessive-compulsive disorder, liver regeneration, thermoregulation and autism [2,7]. Low level of 5-HT can lead to depression, migraines, anxiety, eating disorder, sudden infant death syndrome (SIDS) and blood clotting etc.…”

In this study, the multiwalled carbon nanotube‐poly (aniline) (MWCNT‐PANI) composite is successfully deposited on the glassy carbon electrode (GCE) by electropolymerization as an efficient and conventional route. The structural and chemical properties of the MWCNT‐PANI was investigated by various spectroscopic and analytical techniques, scanning electron microscopy (SEM), X‐Ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS). After that, the electrochemical oxidation behavior of serotonin (5‐HT) in phosphate buffer solution (pH 7.4) was examined using cyclic voltammetry (CV). Besides, the MWCNT‐PANI/GCE used for the detection of 5‐HT with linear concentration range (1.0×10−7–1.2×10−5 mol L−1), low limit of detection (3.3×10−8 mol L−1) under differential pulse voltammetric (DPV) conditions. The proposed electrochemical sensor based on MWCNT‐PANI is both time and cost effective, has good reproducibility, high selectivity as well as stability for 5‐HT determination. The developed composite electrode was used to detect 5‐HT in synthetic urine sample and satisfactory results were obtained with high recoveries.

“…In case of breast cancer cells, they change the expression of serotonin receptor, which contributes to abnormal cell growth, and avoid tumor suppressive actions of serotonin . Therefore, the monitoring of their concentration is important for early diagnosis of breast cancer as an additional prognostic parameter . In addition, high level serotonin may affect the dopamine uptake by its transporter .…”

An electrochemical sensor based on the conducting polymer composite with a palladium complex (Pd(C2H4N2S2)2) was developed for the detection of serotonin and dopamine simultaneously in the breast cancer cell and human plasma samples. The proposed sensor was fabricated using the Pd(C2H4N2S2)2 complex‐anchored poly2,2 : 5,2‐terthiophene‐3‐(p‐benzoic acid) (pTBA) layer on the AuNPs decorated reduced graphene oxide (AuNPs@rGO) substrate, which revealed the enhanced anodic current of the target species. The sensor probe was characterized by electrochemical and surface analysis methods. The experimental parameters affecting the sensor performance were optimized, in terms of AuNPs@rGO concentration, the number of electropolymerization cycle for pTBA, immobilization time of Pd(C2H4N2S2)2, and pH. The dynamic ranges for serotonin and dopamine were obtained from 0.02 to 200 μM, and from 0.1 to 200 μM with the detection limit of 2.5, and 24.0 nM, respectively. The reliability of proposed sensor was evaluated using cancer cell lines for the clinical applications.

BACKGROUND Research on electrode materials with high electrochemical activity is of great importance for the electrochemical oxidation technique. In this work, an electrode comprising titanium dioxide nanotubes with tin oxide antimony (TiO2‐NTs/SnO2—Sb) with carbon aerogels (TSS‐CAs) was fabricated and used to degrade three isomers of dihydroxybenzenes. RESULTS It was observed that the TSS‐0.5%CAs electrode prepared with 0.5 wt% CAs possessed prominent pore structure and a larger specific surface area of 180.83 m2 g−1. Electrochemical measurements revealed that the TSS‐0.5%CAs electrode had enhanced electrochemical activity, larger electroactive area, and higher oxygen evolution potential. Relevant operational parameters including initial contaminant concentration, pH, electrolyte concentration and current density had significant effects on the electrocatalytic performance of the TSS‐CAs electrode. CONCLUSION It was demonstrated that a proper content of carbon aerogel could improve the structure and electrochemical performance of the TSS‐CAs electrode. The removal of catechol was higher than that of hydroquinone and resorcinol during electrochemical oxidation, due to its lower Gibbs free energy barriers. Oxidation of intermediates of dihydroxybenzenes by the TSS‐CAs electrode also was confirmed. © 2019 Society of Chemical Industry
