abstract = {The depletion interaction between a probe sphere and a flat
wall induced by fd virus is investigated by means of total
internal reflection microscopy (TIRM). The viruses serve as
a model system for monodisperse, rod-like colloids. We find
that the experimental potentials are well described by the
first-order density approximation up to an fd content of
several overlap concentrations. This is in accordance with
higher order density theory as confirmed by numerical
calculations. Since the first-order analytical description
still holds for all measurements, this exemplifies that
higher order terms of the theory are unimportant for our
system. Comparing the potentials induced by wild-type fd to
those induced by a more rigid fd variant, it can be shown
that the influence of the virus stiffness is beyond our
experimental resolution and plays only a negligible role for
the measured depletion potentials.},
