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 […]

Generation-Collection Electrochemistry Inside a Rotating Droplet

We just had a paper published in Analytical Chemistry concerning generation-collection electrochemistry inside a rotating droplet. This is a continuation of the investigation of the rotating droplet as a small volume hydrodynamic system that was published last year in Electrochem. Commun. In this paper we generation-collection electrochemistry, meaning that we […]

Rotating droplet as a new alternative for small volume electrochemical measurements 1

A paper from Magda’s work with a rotating droplet as alternative to rotating disc electrodes for electrochemical measurements in small volumes was just accepted in Electrochemistry Communications. This is a development of an idea from Limoges’s group in Paris, where they used a rotating disc electrode (RDE) to spin a […]

Compatibility of organic solvents for electrochemical measurements in PDMS-based microfluidic devices

We just had a new paper published in Microfluidics and Nanofluidics concerning the compatibility of some organic solvents with PDMS-based microfluidic devices. In a well-known study (cited ~1600 times) the Whitesides-group argued that how much PDMS swells in a solvent is a good indication of how compatible that solvent is with […]
