Abstract

Diffusion of polymer-coated nanoparticles was studied using fluorescence correlation spectroscopy (FCS). The fluorescence from the sample was collected using objective lens and was detected using thermoelectrically cooled photomultiplier tubes. The results show decrease in diffusion coefficient at the highest concentration of the given sample because of aggregation of the particles while no dependence was observed in the concentration ranging between 0.06-0.55 nM.
