We are interested in the detection of bacterial species via microdevices for rapid and early detection or identification of bacterial growth and antibiotic resistance (collab. Laboratoire de Photophysique Photochimie Supra- et Macromoléculaires PPSM ENS Paris-Saclay, Institut de Chimie Physique). We are developing ratiometric and pH-sensitive luminescent nanoparticles (NPs), surface engineering and grafting of these sensitive NPs (thesis G. Moran, P. Miaobo). These NPs can be modulated (core – surface), and will ultimately be integrated into a microfluidic system and a sample pre-treatment and concentration system (thesis in progress, M. Harris). We have opened up a line of research into the characterization and applications of QDs for detecting bacterial contamination of fluids (PPSM ENS Paris-Saclay partnership – thesis R. Sobczyk) or glyphosate detection. As part of this work, the team is involved in the scientific responsibility of the Centre de Photonique pour la Biologie et les Matériaux (CPBM, see Plateforms).
In a consortium with Sophia-Antipolis University and the Lavoisier Institute in Versailles, we are also developing luminescent superhydrophobic surfaces as antibacterial or anti-biofilm coatings. We target pathogenic strains (S. aureusand P. aeruginosa).
