“…[27][28][29][30][31] For example, the anionic surfactant sodium dodecyl sulfate (SDS) has been used to increase the detection limits in electrochemical studies. [32][33][34][35] It is appropriate for surface immobilization, acting as a minute conduction center; and allowing electron transmission.

Electrochemical techniques were used for estimating xylazine HCl (XLZ) in bulk powder, medicinal manufacturing and human serum. Electro-oxidation of XLZ at carbon multiwalled nanotube (MWCNT), 1-n-butyl-3-methylpyridinium hexafluorophosphate ion crystal (BMH) and sodium dodecyl sulfate (SDS) MWCNT-BMH-SDS electrode in 0.04 M Britton-Robinson buffer (BR) with pH 7.0, was studied in numerous buffer structures and at different pH values. The experimentation and instrumental parameters to assessable commitment of XLZ had been optimized, and a detection limit was observed as 4.80 nM. The precision and accuracy for the recognized method was tested by retrieval studies with good repeatability and reproducibility of the estimated method. The projected method was practiced successfully to the dosage form and spiked serum.

“…Lower oxidation peak potential and higher peak current density are two important parameters of an anode catalyst for good electrocatalytic activity. The table shows that though the electrocatalytic activity of rGO/PEDOT : PSS is lower than that reported in and , which is due to presence of platinum nanoparticles with graphene/conducting polymer nanocomposites, the rGO/PEDOT : PSS may act as an efficient platinum free electrocatalyst towards methanol oxidation as compared to that reported in the literature . The enhanced electrocatalytic activity of the nanocomposite is ascribed to that presence of rGO which provides enhanced surface area and electroactive sites for methanol electro‐oxidation.…”

Increasing demand of alternative energy sources leads to the development of new electrocatalytic materials for fuel cells. In present work, we report the synthesis of rGO/PEDOT : PSS (reduced graphene oxide/ Poly (3,4‐ethylenedioxythiophene) : Polystyrene sulfonate) nanocomposite by in‐situ polymerization method using EDOT as precursor and the nanocomposite is used as anode catalyst for methanol oxidation. Structural and chemical characterizations such as XRD, FTIR and Micro‐Raman confirm the formation of the nanocomposite. From TEM image, growth of nanofibrous PEDOT : PSS on rGO nanosheets is observed. Electrochemical characterizations of rGO/PEDOT : PSS/ITO electrode are performed by Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS) and Chronoamperometry (CA) measurements. Methanol oxidation reactions are performed in 0.5 M NaOH solution. The anodic current of the nanocomposite coated ITO is found be 37.5 mA at 0.59 V due to methanol electro‐oxidation and retentivity of the electrode is 92 % of initial scan after 800 cycles. The chronoamperometric results reveal that the nanocomposite modified electrode exhibits better stability with retention factor of 42.4 % up to 3000 seconds. The rGO/PEDOT : PSS/ITO electrode exhibits enhanced electrocatalytic activity towards methanol oxidation reaction due to larger surface area and excellent conductivity of rGO nanosheet.

The sensitivity enhancing properties of sodium dodecyl sulphate (SDS) and multi‐walled carbon nanotubes (MWCNTs) were associated to construct a nanosensor based on carbon paste electrode (CPE) by adopting drop cast method. The drop cast method makes use of minimum modifier and the entire modified surface of the sensor is available for the analyte. Surface characterization of the electrodes was carried out using FE‐SEM and EDX. EIS was used for the electrochemical characterization. We report for the first time the electrochemical analysis based on the oxidation of the ‐OH group of a novel drug, alpha‐hydrazinonitroalkene (I) which was found to have antibacterial and antimicrobial properties. The electron transfer kinetic parameters such as the charge transfer coefficient α and heterogeneous rate constant k′ were calculated and they have been found to be 0.64 and 9.62 × 10−2 cm s−1 respectively. The linear response ranges for (I) obtained at this sensor are 1.0 × 10−7 M − 7.0 × 10−7 M and 1.0 × 10−6 M – 4.5 × 10−5 M with a detection limit of (7.03 ± 0.41) × 10−8 M (S/N=3). The interference study suggested that the sensor was free from 1000‐fold excess of UA in the determination of (I). It was important to note that the sensor completely eliminated Ascorbic acid (AA) signal which offered a significant analytical advantage for the determination of the drug at this sensor. The practical usefulness of the modified sensor was demonstrated by the analysis of (I) in blood serum.
