“…The DPV results showed a linear relationship between the concentration of sertraline and the anodic peak current in the range from 0.1 to 85 µM. A La 2 O 3 /Co 3 O 4 nanocomposite modified screen-printed electrode enabled the determination of sertraline in a pH 7 phosphate buffer also using DPV [14]. In this case, the anodic peak current was increased linearly with the drug concentration in the range from 5.0 to 400.0 µM.…”

The electrochemical characterization of sertraline at gold electrode was examined by cyclic voltammetry measurements (CV) in pH 8.4 bicarbonate buffer. Then Au electrode was evaluated for the quantitative determination of sertraline using square wave voltammetry (SWV). To enhance the sensitivity during the drug determination, (2-hydroxypropyl)-β-cyclodextrin (HPβCD) and β-cyclodextrin (βCD) inclusion complexes were employed. Using the proposed SWV technique, the anodic current peak was linear within a concentration range of 0.1-0.5 µM with a limit of detection (LOD) of 2.0 × 10 -8 M and a limit of quantification (LOQ) of 6.7 × 10 -8 M. In the case of inclusion complex of the sertraline with HPβCD, a good linearity range of 0.1-0.9 µM was obtained with a LOD of 2.6 × 10 -8 M and a LOQ of 8.8 × 10 -8 M. The gold electrode revealed the same linearity range for inclusion complex of the sertraline with βCD with a LOD and a LOQ being 2.6 × 10 -8 and 8.6 × 10 -8 M, respectively. Comparing the regression equations, it can be concluded that the sensitivity in the presence of inclusion complex can be up to 5 times higher. The applicability of the developed method was confirmed by the analysis of this drug in pharmaceutical formulation and in human serum spiked with sertraline standard. The comparison to HPLC method was successfully performed.

“…With the extraordinary catalytic properties of metal oxide nanoparticles and low toxicity of lanthanum ions, Mohammadi and group [ 31 ] reported a simple, yet economical, electrochemical sensor for the detection of sertraline. The La 2 O 3 /Co 3 O 4 nanocomposite was prepared by the impregnation of La 2 O 3 nanoparticles onto the surface of Co 3 O 4 hexagonal nanosheets and was deposited on an SPE.…”

“…To overcome these challenges, functional material and/or nanomaterials known for their unique physicochemical and electrical properties have been incorporated into the surfaces of the bare working electrodes providing the modified electrode with new and fascinating properties. These impact strongly on the application of electrochemical sensors and biosensors through better selective and sensitive detection, limited interference of other biomolecules, improved reproducibility and increased usage, and the reduced effects of fouling [ 31 ]. Studies in material and nanomaterial sciences have progressed significantly, where materials with controlled dimensions and morphologies as well as surface charges and other physicochemical properties have been fabricated which can then be customised to specific analytes for electrochemical sensing.…”

Review on Surface-Modified Electrodes for the Enhanced Electrochemical Detection of Selective Serotonin Reuptake Inhibitors (SSRIs)

Selective serotonin re-uptake inhibitors (SSRIs) are one of the most commonly prescribed classes of antidepressants used for the treatment of moderate to severe depressive disorder, personality disorders and various phobias. This class of antidepressants was created with improved margins of safety. However, genetic polymorphism may be responsible for the high variability in patients’ responses to treatment, ranging from failure to delayed therapeutic responses to severe adverse effects of treatment. It is crucial that the appropriate amount of SSRI drugs is administered to ensure the optimum therapeutic efficacy and intervention to minimise severe and toxic effects in patients, which may be the result of accidental and deliberate cases of poisoning. Determining SSRI concentration in human fluids and the environment with high sensitivity, specificity and reproducibility, and at a low cost and real-time monitoring, is imperative. Electrochemical sensors with advanced functional materials have drawn the attention of researchers as a result of these advantages over conventional techniques. This review article aims to present functional materials such as polymers, carbon nanomaterials, metal nanomaterials as well as composites for surface modification of electrodes for sensitive detection and quantification of SSRIs, including fluoxetine, citalopram, paroxetine, fluvoxamine and sertraline. Sensor fabrication, sensor/analyte interactions, design rationale and properties of functional material and the electrocatalytic effect of the modified electrode on SSRI detection are discussed.

The sensor could detect PPH concentrations as low as 0.08 μM.…”

Herein, Ag@CDs nanocomposites were utilized for the detection of propranolol hydrochloride (PPH). Structural characterization of the nanocomposites was performed using UV-Vis., spectroscopy, dynamic light scattering, zeta potential, and contact angle measurements. Electrochemical analysis of the prepared electrode Ag@CDs/ITO was done using electrochemical impedance spectroscopy and cyclic voltammetry. Three electrodes were fabricated on same ITO substrate through selective etching of ITO followed by deposition of different materials on each electrode. To the best of our knowledge, miniaturization of the bulky electrochemical measurement setup has not been reported yet. Moreover, the proposed setup was able to give good limit of detection of 0.38 μM and exhibited linear response in the range of 5-45 μM PPH. Also, the sensor was functional in artificial urine samples showing 80-100% recoveries. The excellent stability, repeatability, and reproducibility of the proposed sensor validate its application in real sample analysis.
