Title: Electrochemistry of single impacts for bacteria sensing
Speaker: Estelle Lebègue
Affiliation: CEISAM Laboratory, Nantes University
Abstract: My current research field deals with the electrochemistry of single impacts for bacteria sensing. In this way, I investigate two electroanalytical strategies for bacteria detection, both based on the electrochemistry of single collisions: i) direct monitoring of the bacterial cell through its own electrochemical activity onto the ultramicroelectrode surface and ii) indirect monitoring of the bacterial activity through detection of secreted species with electrochemistry of single redox liposomes nano-impacts. My research project intend to explore the activity and behavior of single bacteria by monitoring their electrochemical response at an ultramicroelectrode. Beyond the detection and identification of a single cell, the goal is to study one bacterium by monitoring in real time its electrochemical activity in different conditions (presence of antibiotics or nutrients) and under stimulations. The originality of this project is to implement the electrochemical single impact method for sensing and monitoring one bacterium in various environments (under stress or growth conditions). My presentation will show some tools and preliminary results for reaching this scientific objective.
