Here we demonstrate the simple construction and characterization of a pyrenyl glycoside-coated 2D MoS2 material composite capable of selectively capturing proteins and live cells on an electrode, as determined by differential pulse voltammetry.
A differential-pulse polarographic (DPP) method was developed for the determination of brodimoprim (BDP) in Michaelis (MCL) buffer. The peak potential (Ep) occurs at 21.33 V (versus SCE) when the pH of the system is 4.0. The voltammetric behaviour in MCL buffer and the mechanisms of the electrode reaction were studied by, e.g., linear sweep voltammetry, cyclic voltammetry and normal-pulse polar...
This work is devoted to the electrochemical characterization of 1,3-diethyl 2-(azulen-1-ylmethylene)propanedioate by cyclic voltammetry and differential pulse voltammetry. The redox processes are established, analyzed and assessed to the particular functional groups at which they take place. The complexation behavior towards lanthanide metal ions (Sm(3+), Eu(3+), Yb(3+), Tb(3+)) was studied by ...

The applicability of differential pulse voltammetry (DPV) and adsorptive stripping voltammetry (AdSV) at a non-toxic meniscus-modified silver solid amalgam electrode (m-AgSAE) for the determination of trace amounts of genotoxic substances was demonstrated on the determination of micromolar and submicromolar concentrations of 3-nitrofluoranthene using methanol 0.01 mol L NaOH (9:1) mixture as a ...
this paper describes the development, electrochemical characterization and utilization of novel modified molybdenum (vi) complex-carbon nanotube paste electrode for the electrocatalytic determination of ascorbic acid (aa). the electrochemical profile of the proposed modified electrode was analyzed by cyclic voltammetry (cv) that showed a shift of the oxidation peak potential of aa about 235 mv ...
in this paper, a nanostructured modified electrode was fabricated by incorporating of 2,2′-[1,9-nonanediylbis(nitriloethylidyne)]-bis-hydroquinone (nnh) as a newly synthesized modifier and tio2 nanoparticles to the carbon paste (mtcpe) and then was used for the electroanalysis of epinephrine (ep). the electrochemical studies were carried out by using cyclic voltammetry, chronoamperometry and di...
Graphene oxide-templated polyaniline (GO-PAN) microsheets were prepared via oxidation polymerization of aniline with graphene oxide (GO) as template. By applying this approach, irregularly shaped GO-PAN microsheets were obtained which was revealed by scanning electron microscopy (SEM). Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) measurements demonstrated that the resulted G...
The redox mechanism of two trisubstituted triazole-linked phenyl derivatives (CL41 and CL42) and a disubstituted triazole-linked phenyl derivative (CL2r50) were studied using cyclic, differential pulse and square wave voltammetry at a glassy carbon electrode. The CL41, CL42 and CL2r50 oxidation is a complex, pH-dependent irreversible process involving the formation of electroactive products tha...
The electrochemical properties of Au and Pd monolayer-protected clusters (MPCs), prepared by dendrimer-templating and subsequent extraction, are described. Differential pulse voltammetry was used to estimate the size of the MPCs, and the results were compared to microscopic data and calculated values. Purification of the extracted Au and Pd nanoparticles was not required to obtain well-defined ...
