Relative number of agglomerated engineered nanoparticles distributed over size. The height of the column represents the number of agglomerated engineered nanoparticles pertaining to a given size interval, divided by the number of all agglomerated engineered nanoparticles measured. Left: the relative number of glucose-suspended TiO₂ agglomerated engineered nanoparticles, right: the relative number of glucose-suspended ZnO agglomerated engineered nanoparticles, as measured by the dynamic light scattering method.
