Group presentation

Our group is located at the National Engineering School of Chemistry, Biology and Physics (ENSCBP). The main activities are focused on the development of new analytical tools and techniques with a special accent on miniaturized systems applied to the study of biological systems and biomedical issues. Our research addresses problems resulting from the ever increasing demands of our modern society concerning various aspects like public health, security and environmental issues. In order to tackle these problems, the discipline of Analytical Chemistry has to evolve constantly and improve its performance.

Distinguishing molecules with almost identical physico-chemical properties, tracking their evolution with a high spatio-temporal resolution, detecting them at the cell or subcellular level in complex environments, are some of the challenges that we work on. With this respect current projects include biofunctionalized nanoparticles, chemical sensors for biology, electrochemistry of biosystems, micro/nanoscale imaging and smart functional nanostructures. In order to work successfully on these topics we have combined in our group an interdisciplinary team with know-how ranging from electrochemistry and optics to organic or colloidal synthesis and cell biology. The resulting synergy is the guaranty for original systems dedicated to contribute to the solution of some of the current problems in the field of Analytical Chemistry.
