abstract = {We report on the dynamics in colloidal suspensions of stiff
viral rods, called fd-Y21M. This mutant filamentous virus
exhibits a persistence length 3.5 times larger than the
wild-type fd-wt. Such a virus system can be used as a model
system of rodlike particles for studying their
self-diffusion. In this paper, the physical features, such
as rod contour length and polydispersity have been
determined for both viruses. The effect of viral rod
flexibility on the location of the nematic-smectic phase
transition has been investigated, with a focus on the
underlying dynamics studied more specifically in the smectic
phase. Direct visualization of the stiff fd-Y21M at the
scale of a single particle has shown the mass transport
between adjacent smectic layers, as found earlier for the
more flexible rods. We could relate this hindered diffusion
with the smectic ordering potentials for varying rod
concentrations. The self-diffusion within the layers is far
more pronounced for the stiff rods as compared to the more
flexible fd-wt viral rod.},
