Electrochemical Studies of Dopamine, Ascorbic Acid and Uric Acid at Lignin Modified Carbon Paste Electrode by Cyclic Voltammetric

Simple detection of gluten in commercial gluten‐containing samples with a novel nanoflower electrosensor made of molybdenum disulfide with comparison of the ELISA method

“…New methods aim to improve gluten analysis with simple, rapid, and in situ detection procedures that provide lower cross‐reactivity as well as better sensitivity with related species (Scherf & Poms, 2016). Electrochemical techniques are inexpensive, portable, easy to operate, and fast; therefore, they are often preferred over the other analytical techniques and have been shown to be useful tools for food detection (Amrutha et al., 2019; Edwin et al., 2021; Eksin et al., 2015; Manjunatha et al., 2009; Prinith et al., 2019; Raril et al., 2018).…”

The mathematical description of dopamine electrochemical oxidation, accompanied by its chemical and electrochemical polymerization

“…Chemically modified electrodes have various advantages, the main of which is the affinity between the modifier and the analyte, reason why they are one of the modern, cheap and tunable electroanalytic tools. For example, for detection of hydroquinonic compounds, various electrode modifiers of a different nature and composition were developed [9][10][11][12][13][14][15]. Some hydroquinonic and quinonic compounds may also serve as electrode modifiers [16][17].…”

A descrição matemática da eletrooxidação de dopamina, acompanhada por sua eletropolimerização

“…Para compostos hidroquinônicos, sendo um deles a dopamina, foram desenvolvidos vários modificadores de elétrodos, desde os polímeros condutores e ésteres específicos até bioobjetos, como casca de banana [9][10][11][12][13][14][15] e, até, os próprios compostos de natureza quinono-hidroquinônica. No entanto, é preciso admitir que dopamina é um composto eletropolimerizável [16], podendo o polímero ser usado, inclusive como o modificador de elétrodos, como foi o caso de polializarina em [17].…”
