  We report the first experimental realization of a rod diffusing in a two
dimensional obstacle field following the single rod dynamics. We use a silver
nanowire as our rod and two types of obstacles: repelling light beams and
polymer pillars. We study the effect of hydrodynamic interactions on the
transport of the rod, comparing both experimental realizations and recent
simulations. We propose a new framework for analyzing the transport through
such systems and predict a new superdiffusive regime of rod transport at high
obstacle concentration and short times.
