“…SWV is the most advanced electrochemical technique, with its advantages including increased sensitivity, short analytical time and the ability to reject non-Faradic current [99]. However, due to its relative complexity, voltammetric data from SWV are less easy to interpret than standard CV, where in most cases, only the net voltammetric peak is analyzed [100].…”

Oxidative stress plays a pivotal role in the pathogenesis of many diseases, but there is no accurate measurement of oxidative stress or antioxidants that has utility in the clinical setting. Cyclic Voltammetry is an electrochemical technique that has been widely used for analyzing redox status in industrial and research settings. It has also recently been applied to assess the antioxidant status of in vivo biological samples. This systematic review identified 38 studies that used cyclic voltammetry to determine the change in antioxidant status in humans and animals. It focusses on the methods for sample preparation, processing and storage, experimental setup and techniques used to identify the antioxidants responsible for the voltammetric peaks. The aim is to provide key information to those intending to use cyclic voltammetry to measure antioxidants in biological samples in a clinical setting.

“…In the last two decades, this methodology is successfully explored to quantify important compounds and to determine kinetic and thermodynamic parameters relevant to relevant lipophilic biological systems that undergo successive multi‐step redox transformation . Moreover, our group and others presented several theoretical models under voltammetric conditions that provide a basis for designing simple methods to recognize a particular electrode mechanism. In addition, plenty of simple methods are provided in our theoretical works allowing elegant access to kinetic and thermodynamic parameters relevant to many lipophilic redox active systems.…”

Square‐wave voltammetry (SWV) of so‐called “surface redox reactions” is seen as a simple and efficient tool to quantify large number of drugs, physiologically active substances and other important chemicals. It also provides elegant methods to get access to relevant kinetic and thermodynamic parameters related to many lipophilic compounds. Moreover, with this technique we can study activity of various enzymes by exploring the “protein‐film voltammetry” set up. In this work, we focus on theoretical SWV features of four complex surface electrode mechanisms, in which the electron exchange between the working electrode and the studied redox substrate takes place in two successive steps. While we present large number of calculated square‐wave voltammograms, we give hints to recognize particular two‐step surface mechanism, but also to distinguish it from other similar mechanisms. We present plenty of relevant aspects of surface two‐step surface EE, two‐step surface ECE and surface catalytic EEC’ mechanisms. Moreover, we present for the first time a series of theoretical results related to two‐step surface EECrev mechanism (i. e. two‐step surface reaction coupled to follow‐up reversible chemical step). The simulated voltammetric patterns presented in this work can bring relevant aspects to resolve some experimental situations met in voltammetry of many redox enzymes and other important substances whose electrochemical transformation occurs in two‐steps.

“…Please do not adjust margins example, the deposition (reduction) of metal ions at the electrode surface occurs at negative potential; then, the reduced species is oxidized (stripped) into the solution again in a positive scan direction 89 . Differential SWV, a hybrid of DPV and SWV, has been developed to unify the advantages of both techniques 90 . Adsorptive anodic stripping voltammetry and adsorptive cathodic stripping voltammetry could be used for analyte detection 91 .…”
