“…the minimum and maximum sweep voltage, the scan rate, and the number of measurement cycles. An example study on LSV has been used to determine VOR levels by implementing simple carbon nanotube modified stencil printed carbon electrodes (CNTs-SP) in pharmaceutical formulations and biological fluids [12]. By implementing LSV, the efficiency and effectiveness of the electrodeposition process can be increased by evaluating the accurate and precise statistics of the measurement result.…”

“…CV studies were used to detect several diseases in the medical field, such as abetalipoproteinemia, cancer, cerebral ischemia, and diabetes [11]. Another study used linear sweep voltammetry (LSV) to determine the levels of vortioxetine hydrobromide (VOR), which is an antidepressant drug with a high binding affinity to various serotonin receptors in the central nervous system [12]. Differential pulse voltammetry (DPV) assists the process of determining and quantifying several contaminant substances of water sources by anthropogenic activity [13].…”

Electrochemical method is often chosen to analyze various bio-chemical reactions due to its operation simplicity with versatile applications. Thus, for this purpose, the procurement of potentiostat, an electrochemical-based analysis instrument, also needs to focus on the low price, but maintaining its rich analysis features. In this paper, we designed a low-cost and portable potentiostat system based on the ESP32 microcontroller. Even with the low-cost system design, it supports various electrochemical measurement methods, i.e. cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV), differential pulse voltammetry (DPV), normal pulse voltammetry (NPV), and the observation of electrochemical current against time based on chronoamperometry measurement method. The potentiostat performance was assessed by the electrochemical signal accuracy and errors. Furthermore, the measurements can also be carried out semi-parallelly within three measurement channels simultaneously. The results showed that it could produce voltammograms with an average accuracy of more than 90%, compared to the commercial Emstat Pico. Even though having this comprehensive and extensive electrochemical analysis, the cost of the total system realization could be downsized to only USD 21.4.

“…The literature survey showed few methods utilizing different techniques for the analysis of VOR, including HPLC, [5][6][7] TLC, 8 spectrophotometry, 9 and voltammetry. [10][11][12][13][14] The published stripping differential pulse voltammetry method used gold nanoparticles/graphene/(AuNPs@GRP) nanocomposite 10 and the other methods employed carbon nanotube-modified stencil-printed electrode, 11 three-dimensional nickel ferrite nanospheres, 12 glassy carbon electrodes modified with hierarchical carbon nanofibers with NiCo nanoparticles, 13 and graphite pencil electrode, 14 which were already used for VOR detection; however, these processes are costly and consume a lot of time. For electrodes, the preparation of the electrode is a very complicated and sophisticated process, which takes a lot of time and requires special precautions to ensure developing electrodes with same repeatability and reproducibility.…”

“…Therefore, voltametric methods may be an alternative approach for VOR determination, considering their ease, low cost, and high sensitivity of measurements. In the literature different types of working electrode, such as carbon-nanotube-modified stencil printed electrode [ 19 ], graphite pencil electrode [ 20 ], glassy carbon electrode modified with gold nanoparticles and graphene [ 21 ], or with three-dimensional nickel ferrite nanospheres [ 22 ] were already used for vortioxetine determination.…”

A new voltammetry method for the highly sensitive antidepressant drug vortioxetine (VOR) is presented using glassy carbon electrodes modified with hierarchical carbon nanofibers with NiCo nanoparticles (eCNF/CNT/NiCo-GCE). The electrochemical behavior of VOR was investigated by cyclic voltammetry, which indicates that its oxidation is an adsorption-controlled process with the exchange of two electrons and one proton. The effects of various factors on the VOR peak, such as supporting electrolyte type, preconcentration time, and potential, or influence of interferents, were tested using the square wave voltammetry technique (SWV). The linear voltametric response for the analyte was obtained in the concentration range from 0.01·10−6 to 3.0·10−6 mol L−1 with the detection limit of 1.55·10−9 mol L−1 for a preconcentration time of 60 s. The proposed method was successfully applied for highly sensitive VOR determination in complex matrices such as tablets, urine, and plasma with good recovery parameter.
