Research Group "MER"

" Electroanalytical Methodologies and Reactivities "



Home> Research Groups > LEM "MER"

The research works of the team are oriented toward two different but complementary directions. The first one is the development and design of new bioelectroanalytical methodologies (bioaffinity electrodes, enzyme-based biosensors, aptasensors, and electrochemical methods for sensitive detection of nucleic acids), including the development of controlled and organized assembly of biomolecules on electrode surfaces, as well as the characterization of biomolecular recognition processes at interfaces. The second one is related to a more fundamental research, where the objectives are to better understand and rationalize the mechanisms of electron transfer/transport in redox proteins or in biomimetic systems, to elucidate the reactivity of redox enzymes not only when they are in a homogeneous solution but also when they are immobilized on the surface of an electrode, and to predict their electrochemical behavior. For all of these studies, we rely on the use of electrochemical techniques such as cyclic voltammetry or spectroelectrochemistry, as well as on the development of theoretical tools (modeling, simulations).
