(a)–(e) Observations from confocal laser microscopy of a depletion flocculated particle system under shear, with, respectively, , 0.5, 1, 5, and 30 . (f) Nondimensionalised radius of clusters versus applied shear rate (as Péclet number). The dotted line marks the onset of slip. For the system  nm, , and . (Reproduced from Ballesta et al.
