The research group in focussed on electrochemistry in hydrodynamic system, such as microfluidics, rotating disk systems and similar. We have two main branches of our research; studies of ion transfer between immiscible liquids mainly in micro­fluidic systems; and studies bioelectrocatalytic processes by enzymes both under static and hydro­dynamic conditions. In addition to this we try to use our setups for analytical studies and for development of the systems themselves. Experiments are complemented with computer simulations, mainly using Comsol.

Ion transfer studies in microfluidics is a relatively new topic that complements the traditional studies usually performed in droplet based systems. We have investigated the anomalous dependence of ion transfer current as a function of flow rate and recently shown that the equations for ion transfer thermodynamics at three phase electrodes in static system can also be used in microfluidics. Ongoing studies involves work on electrochemical processes in droplet-based microfluidic systems.

RDE-BODThe study of enzyme reactions are performed both with an eye towards applications in sensing and biofuel cells as well as for fundamental studies of enzyme kinetics. We perform measurements using both rotating disk electrodes (RDE) as well as in microfluidic systems. Both of these systems are forced convective systems; although microfluidics offers a larger array of possible electrode materials and easier modification, RDE is more user friendly.

We are also working on developing new materials for electrode modification that ensures proper immobilisation and electron transfer between the enzyme and the electrode.

Recently we have started up a small project to merge electrowetting on dielectrics (EWOD) with electrochemistry.
