(a) Voronoi diagram showing localized diffusion coefficients in the middle cross section of the FCC particle. Each track’s center of mass, indicated with a dot, is surrounded by an area that is closer to that track than to any other. The color of each area indicates the diffusion coefficient, with areas around immobile tracks being white. (b) Diffusion coefficients of each type of track. The gray rectangle includes diffusion coefficients falling within the localization uncertainty of the single-molecule analysis. The inset Voronoi diagram shows the spatial distribution of each track type.
