      abstract     = {In some applications the dye distribution within
                      fluorescently labeled nanoparticles and its stability over
                      long periods of time are important issues. In this article
                      we study numerically and experimentally the applicability of
                      fluorescence correlation spectroscopy (FCS) to resolve such
                      questions. When the size of fluorescently labeled particles
                      is comparable to or larger than the confocal volume, the
                      effective confocal volume seen in FCS experiments is
                      increasing. Such an effect has already been studied for
                      uniformly labeled spherical particles. In this work we
                      analyze the form of the FCS correlation functions (CFs) for
                      core-labeled and shell-labeled core–shell particles. For
                      shell-labeled particles an additional fast decay was found
                      both in simulations and in experiments on custom-made
                      surface-labeled particles. Universal scaling of FCS
                      correlation times based on the squared ratio of the labeled
                      part radius of gyration to the Gaussian radius of the beam
                      profile was found. Recipes based on the analysis of
                      simulated CFs, proposed for interpretation of experimental
                      results, were successfully applied to the FCS results on
                      suspensions of large core-labeled and surface-labeled
                      particles.},
