Abstract
In this contribution, we will report on a novel technique recently developed at Institut Langevin that enables multiplexed and super-resolved fluorescence lifetime imaging at the single-molecule level (smFLIM) with a field of view of ~10 µm2 and a localization precision of ~15 nm. Our method combines the use of an EMCCD camera for the localization of photoactivatable single molecules (as usually done in SMLM) and a linear array of single-photon avalanche diodes (SPADs) for time-resolved measurements. Our method can be used for LDOS imaging of disordered and deterministic structures with nanometer-sized features and extensions going from a few hundred nanometers to several microns, with a dynamic temporal range spanning from ns to ms. We will show how smFLIM allows the study of simple nanostructures such as a silver nanowire and complex nanostructures, such as periodic arrays of hollow gold truncated nanocones (nanochimneys).
