Electrochemical Detection of Dopamine and Serotonin in the Presence of Interferences in a Rotating Droplet System

After quite a bit of work Magdalena published her research on using the rotating droplet for detection of neurotransmitters. The key point is that by using the rotating droplet, we can perform hydrodynamic measurements in volumes of only a few tens of microliters. Combining this with an electrode modification that […]

Anodic fabrication of nanostructured CuxS and CuNiSx thin films and their hydrogen evolution activities in acidic electrolytes

This is the latest paper in Vishwanath’s collaboration with his former group in India. In this study, they describe a simple route for direct fabrication of nanostructured copper sulphide and hybrid copper–nickel sulphide thin film electrocatalysts by direct anodization of reactive metal electrodes in sulphide ion containing electrolytes. This method […]

Facilitated cation transfer at a three-phase junction and its applicability for ionophore evaluation

We’re on a roll. Another cation transfer paper was accepted1, also in Electrochimica Acta. This is work done by Marta and our undergrad student Julia. They were investigating transfer of cations at the three-phase junction driven by reduction of the fullerene C60 and facilitated by the addition of ionophores to […]

Electrochemistry of selected quinones at immiscible n-octyl-2-pyrrolidone/aqueous interface using a three-phase electrode system

Vishwanath’s research on cation transfer at a three-phase junction was just published1 in Electrochimica Acta. This paper looks at transfer of cations driven by a redox reaction in an organic droplet immobilised on the electrode surface. The droplet is small enough not to cover the whole electrode area, so a […]

Pencil Lead as a Material for Microfluidic 3D-Electrode Assemblies

After long, hard effort we finally published* our research on pencil lead electrodes as electrode arrays in a microfluidic system. This was first intended as an easy-to-assemble system that could be used e.g. in experiments for high-school students or undergrads. However, from that initial, simple idea it turned out to […]

Interactions of bacteriophage T4 adhesin with selected lipopolysaccharides studied using atomic force microscopy

A paper was recently published in Scientific Reports about atomic force microscopy, investigating interactions between bacteriophages and bacteria. Or, at least, as the title says, between T4 adhesin with lipopolysaccharides from bacteria. This was done by modifying an AFM tip with the adhesin from the bacteriophage T4 and using this tip to […]

Paper-based system for ion transfer across the liquid-liquid interface

In a paper just accepted for publication in Analytical Chemistry Marta, Emilia, and Martin, together with Damien Arrigan from Curtin University, and our former intern Alexandra Pacowska, show how ion-transfer across the liquid-liquid interface can be studied in a paper-based system. One of the problems when studying ion-transfer between an organic […]
