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 […]

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 […]

Poland-China Symposium

Last week Martin took part in the 1st Poland-China Bilateral Scientific Symposium on Emerging Technologies in Photonics and Electronics organised in Shenzhen, China by Prof. Mateusz Smietana from Warsaw University of Technology and Prof. Liyang Shao from Southern University of Science and Technology (SUSTech). The goal of the meeting was […]
