Research & SKILL

Members of the team "Dynamics, Nanoscopy and Chemometrics" are interested in micro- and nano-imaging of photoactive bio-systems, particularly the study of the photochemistry & photodynamics of molecules, proteins and emissive organic and hybrid nanoparticles for super-resolution fluorescence biological imaging. Our speciality is hyperspectral & super-resolved nanometer-scale imaging of ultrafast processes, and the development of new instrumentation and methodologies for the analysis of these hyperspectral super-resolved data. Our goal is to build detailed photochemical and photophysical models of new and commercial photo-active systems to optimize their use and the development of new bio-materials.
