This review explores the question whether chemometrics methods enhance the performance of electroanalytical methods. Electroanalysis has long benefited from the well-established techniques such as potentiometric titrations, polarography and voltammetry, and the more novel ones such as electronic tongues and noses, which have enlarged the scope of applications. The electroanalytical methods have...

Recent work has reported the first electroanalytical detection of pindolol using reduced graphene oxide (RGO) modified glassy carbon electrodes [S. Smarzewska and W. Ciesielski, Anal. Methods, 2014, 6, 5038] where it was reported that the use of RGO provided significant improvements in the electroanalytical signal in comparison to a bare (unmodified) glassy carbon electrode. We demonstrate, for...

Ensembles of nanoscopic disk-shaped electrodes have been shown to offer enhancements in electroanalytical detection limits relative to electrodes of macroscopic dimensions (e.g., disk electrodes with diameters of ∼1 mm). Enhancements in electroanalytical detection limits have also been observed at macroscopic electrodes that have been coated with films of ion-exchange polymers. In this paper we...

In this overview we explore the electroanalytical sensing of important chemical reagent hydrazine, highlighting plethora electrochemical strategies utilised from first reports in 1951 to present day.

Ascorbic acid is a water-soluble vitamin essential in human nutrition, an antioxidant, scavenger of free radicals biological systems, and cofactor several enzymes. The reference range for ascorbic healthy people 6 - 20 mg L-1. variable concentration within biology fluids was found clinical investigations to be metric assessing the exact amount oxidative stress body's metabolism. Electroanalytic...

In this overview, we explore the electroanalytical determination of theophylline. Theophylline finds use as a bronchodilator for treating diseases such asthma and chronic obstructive pulmonary disease (COPD). There is need to measure concentration theophylline in pharmaceuticals QA/QC purposes well plasma samples ensure doses are at correct therapeutic levels. If levels deviate from (10–20 µg/m...
