Advanced Electroanalysis for Electrosynthesis

ACS Organic & Inorganic Au, 2023
Electrosynthesis is a popular, environmentally friendly substitute for conventional organic methods. It involves using charge transfer to stimulate chemical reactions through the application of a potential or current between two electrodes. In addition to electrode materials and the type of reactor employed, the strategies for controlling potential and

Bipolar (Bio)electroanalysis [PDF]

Annual Review of Analytical Chemistry, 2021
This contribution reviews a selection of the most recent studies on the use of bipolar electrochemistry in the framework of analytical chemistry. Despite the fact that the concept is not new, with several important studies dating back to the middle of the last century, completely novel and very original approaches have emerged over the last decade ...

Heroin detection in a droplet hosted in a 3D printed support at the miniaturized electrified liquid-liquid interface

Scientific Reports, 2022
Simple sensing protocols for the detection of illicit drugs are needed. Electrochemical sensing is especially attractive in this respect, as its cost together with the analytical accuracy aspires to replace still frequently used colorimetric tests.

Label-free electrochemical monitoring of DNA ligase activity [PDF]

, 2008
This study presents a simple, label-free electrochemical technique for the monitoring of DNA ligase activity. DNA ligases are enzymes that catalyze joining of breaks in the backbone of DNA and are of significant scientific interest due to their essential

Electrochemistry at the liquid–liquid interface rediscovers interfacial polycondensation of nylon-6,6

Electrochemistry Communications, 2020
The interfacial polymerization of nylon-6,6 is studied at the polarized liquid–liquid interface. The optimal conditions (concentration of reagents in a biphasic system, pH of the water phase, voltammetric cycling) are used to modify the interface ...
