RESEARCH TOPICS
Nos recherches visent à développer des capteurs électrochimiques pour la détection et la quantification d’espèces d’intérêt au sein de matrices complexes. La méthodologie employée est la suivante : 1/ la modification d’électrodes par des fonctionnalités spécifiques des cibles visées ; 2/ l’optimisation du design des interfaces en vue de l’amélioration des performances analytiques des capteurs.
Les travaux actuels visent essentiellement deux domaines d’applications :
– le dosage des éléments-traces métalliques, et plus particulièrement du mercure, dans les eaux de surface (lacs, rivières, …), avec des électrodes en carbone fonctionnalisées par des sels de diazonium et des nanoparticules d’or ;
– le dosage de biomarqueurs du stress oxydatif, tels que les acides urique et ascorbique, dans les fluides biologiques (sang, urine) avec des électrodes fonctionnalisées par un polymère biocompatible.
Research interest :
– Capteurs électrochimiques pour le dosage des éléments-traces métalliques dans les eaux de surface
– Capteurs électrochimiques pour le dosage d’antioxydants
– Mots-clés : capteurs électrochimiques – électrodes modifiées – diazoniums – nanoparticules d’or – métaux lourds – stress oxydatif
