FRAP FLIM FAIM – an integrated multimodal fluorescence microscopy technique to study diffusion in cell membranes

In fluorescence microscopy, obtaining as much information as possible from the fluorophores in the sample in a single experiment is of great interest. We employ Time-Correlated Single Photon Counting (TCSPC) to simultaneously perform Fluorescence Lifetime Imaging (FLIM), Time-Resolved Fluorescence Anisotropy Imaging (tr-FAIM), and Fluorescence Recovery After Photobleaching (FRAP). FLIM yields information about the fluorescence lifetime, which can be sensitive to the microenvironment of the fluorophore. tr-FAIM can monitor the depolarization of the fluorescence, which can be due to rotational motion, or homo-FRET. FRAP shows the translation of the fluorophore. The project will focus on the use of this technique to study rotational and translation diffusion in heterogeneous media such as artificial cell membranes. It is an interdisciplinary project at the boundaries of physics, chemistry and biology.
