Super-resolution imaging techniques enable to image objects with a resolution at the nanometer length scale (~10 nm), well below the classical limit imposed by the diffraction of light (~200 nm). Among these techniques, single-molecule localization microscopy (SMLM) approaches are based on the capacity of detecting single-molecules and the ability of switching on and off fluorescent emitters. At Institut Langevin, ESPCI Paris PSL, we have further developed such concept and conceived a novel microscopy system capable of simultaneously detecting single fluorescent molecules as well as their fluorescence lifetime, and thus obtaining super-resolved fluorescence lifetime images (smFLIM). So far, we have studied light-matter interactions in plasmonic and dielectric nanostructures and obtained super-resolved images of the local density of electromagnetic states of silver nanowires, gold nanocones and GaP nanodimers. We are looking for a motivated student to work with us to explore a new application of smFLIM, that is the study of temperature increase in nanostructured samples based on single-molecule fluorescence modification. smFLIM has the potential to address this challenge, by using stochastically photoactivatable molecules that have a temperature-dependent fluorescence. The sensitivity of single-molecules’ fluorescence to this parameter will be explored in the internship and its application to the map of plasmon induced temperature enhancement will be investigated.
