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.

KEY Words

  • Photochemistry, Photochromism, Time-resolved spectroscopy, Fluorescence, Imaging, Single molecule, Polarisation
  • Chemometrics, Data analysis, Image analysis, Hyperspectral, Spectral unmixing, Super-resolution, Deconvolution
