Rotational dynamics of colloidal tracer spheres in suspensions of charged rigid rods

Abstract:

The concentration dependence of the short-time rotational diffusion coefficient Hsr(φ) of charged tracer spheres with radii of 67, 103, and 137 nm in suspensions of charged rigid rods was measured as a function of the ionic strength. The ionic strength dependence was qualitatively similar to that observed previously for tracer-host sphere mixtures. Reducing the Debye screening length κ-1 from 20 to 2.3 nm had no significant effect on the tracer mobility, but a further reduction of κ-1 to 0.96...
