The Cover Feature depicts the schematic of micropipette apparatus along with electrolytically induced facilitated ion transfer process as well an example differential pulse voltammetry (DPV). This is overlaid onto a photo Newfoundland coast at sunset. More information can be found in Aricle by Q. Jiang et al.

A sensitive electroanalytical method for determination of acetaminophen (ACT) in paracetamol tablet has been developed and validated. Cyclic voltammetry (CV) was used to study the electrochemical behaviour of paracetamol, while differential pulse voltammetry (DPV) was used to determine ACT. Screen printed carbon electrode was used for the analysis. Determination of all parameters in paracetamol...

Background: This research was focused on the development of a quick, simple, precise, and cost-effective voltammetric method for quantifying dosulepin. Materials Methods: The antidepressant drug (dosulepin) assessed in pharmaceutical formulations using square wave (SWV) Differential pulse (DPV) techniques at glassy carbon potentiometric working electrodes (GCE). Results: Dosulepin demonstrated ...

A new modified glassy carbon electrode (GCE) based on a synthesized N-(2-aminoethyl)-4,4'-bipyridine (ABP) was developed for the determination of Ag(I) by differential pulse voltammetry (DPV). ABP was covalently immobilized on GC electrodes surface using 4-nitrobenzendiazonium (4-NBD) and glutaraldehyde (GA). The Ag(I) ions were preconcentrated by chemical interaction with bipyridine under a ne...

the electrochemical oxidation and determination of tryptophan (trp) and glutathione (gsh) in the presence of catechol as a homogeneous redox in the aqueous medium were investigated at the surface of a carbon paste electrode modified with multi-walled carbon nanotube (mwcnt-cpe) using cyclic voltammetry (cv), double step potential chronoamperometry and differential pulse voltammetry (dpv) techni...

In the present work, a new sensor for morphine (MO) measurement, based on modification of screen-printed carbon electrode (SPE) by using magnetic core shell manganese ferrite nanoparticles was reported. The electrochemical behaviour of MO was investigated in phosphate buffer solution (pH 7.0) by voltammetry. The electrochemical response of the modified electrode toward morphine was studied by m...

Double-stranded (ds) complexes of poly(C) with poly(G) and poly(G,I) were studied using differential pulse polarography (DPP) and differential pulse voltammetry at a pyrolytic graphite electrode (DPV). The complex formed by copolymer was found to be DPP inactive. On the other hand, poly(G).poly(C) yielded a small DPP peak corresponding to single-stranded (ss) poly(C). It was suggested that ss p...

Gold nanoelectrodes ensembles (NEEs) have been prepared by electroless plating of Au nanoelectrode elements within the pores of a microporous polycarbonate template membrane. Cyclic voltammograms recorded in (ferrocenylmethyl) trimethylammonium hexafluorophosphate (FA(+) PF(6)(-)) solutions showed that these NEEs operate in the "total-overlap" response regime, giving well resolved peak shaped v...

A cuprous oxide (Cu₂O) thin layer served as the base for a non-enzymatic glucose sensor in an alkaline medium, 0.1 NaOH solution, with a linear range of 50-200 mg/dL using differential pulse voltammetry (DPV) measurement. An X-ray photoelectron spectroscopy (XPS) study confirmed the formation of the cuprous oxide layer on the thin gold film sensor prototype. Quantitative detection of glucose in...
