The current endeavour presents the poly(L-serine) modified carbon paste electrode (PLSMCPE) fabricated through an electropolymerization methodology for the electrochemical analysis of catechol (CC). Field emission scanning electron microscopy (FE-SEM) images of unmodified and PLSMCPE were examined to study the surface structure and the formation of polymer layer on the electrode surface. The PLSMCPE was functionalized for the voltammetric detection and quantification of CC in 0.2 M phosphate buffer solution (PBS) with a pH of 6.5. In contrast to unmodified electrode the PLSMCPE presented to have nine-fold enhancement in peak current and shift in anodic peak potential towards negative domain. The CV method showed good linear correlation between the concentration of CC and the oxidation peak current in the range from 2-50 μM, and the corresponding limit of detection (LOD) and limit of quantification (LOQ) were achieved to be 0.259 μM and 0.869 μM, respectively. Furthermore, this sensor is used to determine the analytical response in the co-existence of CC and hydroquinone (HQ). The modified electrode is effectively functionalised for the analysis of CC in coffee powder sample.

“…Electropolymerization and surfactant immobilization are two different techniques used for improving the electrode sensing performance. These techniques were commonly used for the surface modification of electrodes because the surfactant drop and polymer layer give an enhanced electrocatalytic effect by controlling over potential [20–22] . In the present work electrochemical methodology was developed for the determination of VA in food sample.…”

Surfactant and Polymer Composite Modified Electrode for the Sensitive Determination of Vanillin in Food Sample

et al. 2021

In this work, the active poly (titan yellow) and octoxynol‐9 modified carbon nanotube paste electrode (PTOMCNPE) was prepared and characterized through a Field emission scanning electron microscope (FE‐SEM), Energy‐dispersive X‐ray spectroscopy (EDX), and Electrochemical impedance spectroscopy (EIS). PTOMCNPEpromotes the detection and quantification of vanillin (VA). The electrochemical parameters such as the number of electropolymerization cycles, effect of surfactant,pH, and scan rate were optimized to get an enhanced current signal for the targetmolecule. Under calibrated conditions, the concentration linearity for vanillin was obtained from 2.0‐40.0 μM using both cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The limitof detection(LOD) for VA was found to be 4.9×10−8 M and 9.31×10−8 M using DPV and CV, respectively. The stable and selective VA sensor was applied to food analysis with excellent recovery.

“…The oxidation potential of DA could distinguish from UA with its good sensitivity, selectivity, and stability. Recently a lot of work has been performed on the topic [28][29][30][31][32][33][34][35][36][37]. The scheme for the oxidations of DA and UA is shown in Fig.…”

A cyclic voltammetric technique was used for electropolymerisation of proline on the surface of carbon paste electrode and for individual and concurrent determination of dopamine (DA) and uric acid (UA). The surface morphology of the developed electrode was studied by using field emission scanning electron microscopy. The modified electrode showed a high current response towards DA as compared to the bare electrode. The developed modified electrode shows good catalytic activity with a different oxidation potential of DA and UA. The electrode process was found to be adsorption controlled. The developed method shows very good stability and reproducibility. Under the optimized conditions, the concentration range is (1‒2)∙10-4 M and the observed detection limit was 4.7∙10-6 M. The developed sensor was applied for the determination of DA in the real sample with a good recovery.
