Abstract
During this HDR defense, I will present my nearly six years of postdoctoral research in chronological order, starting with my experience in the group of Prof. Daniel Bélanger at the Université du Québec à Montréal, where I worked on the catalytic effect of pyridinium cation derivatives on the electrochemical reduction of CO2 in aqueous media and at various electrode materials. My second postdoctoral experience was in the group of the late Prof. Allen J. Bard at the University of Texas at Austin, where I worked on the electrochemical detection of soft nanoparticles by single collision onto the ultramicroelectrode surface. My third postdoctoral contract was in the group of Dr. Frédéric Barrière at the Institut des Sciences Chimiques de Rennes, where I worked on the design of biomimetic membranes for the incorporation of ion-transporting proteins. I continued my postdoctoral work in Rennes funded by a Marie Skłodowska-Curie European individual fellowship focused on the study of membrane proteins in electroactive bacteria probed at modified electrodes. Since I was recruited as an Associate Professor at the CEISAM laboratory at the University of Nantes, I have been developing my own research on single-impact electrochemistry for analyzing electroactive bacteria and redox liposomes. In the final section, I present my research project on the nano-electrochemistry of an electroactive bacterium, outlining the prospects for the work I hope to develop in the short and medium terms.
