    A novel method using PEDOT (poly(3,4-ethylenedioxy) thiophene) modified electrode was developed for the determination of caffeic acid (CA) in wine. Cyclic voltammetry (CV) with the additions standard method was used to quantify the analyte at PEDOT modified electrodes. PEDOT films were electrodeposited on Platinum electrode (Pt) in aqueous medium by galvanostatic method using sodium poly(styrene-4-sulfonate) (PSS) as electrolyte and surfactant. CV allows detecting the analyte over a wide concentration range (10.0 nmol l(-1) -6.5 mmol l(-1)). The electrochemical method proposed showed good statistical and analytical parameters as linearity range, LOD, LOQ and sensitivity. (C) 2014 Elsevier Ltd. All rights reserved

    Serotonin (5-HT) is an important neurotransmitter that plays important biological roles in various areas of the body. 5-HT is known to influence key neurological traits, such as anxiety [1], but also plays a key role in driving gastrointestinal motility and platelet aggregation. Serotonin (5-HT) is a key neurotransmitter that is found in the brain, blood and gastrointestinal tract. Due to the interest in measuring this important biogenic amine in these various environments, measurements have been conducted without understanding the influence of the matrix on the stability of recordings
