      abstract     = {Aggregated suspensions of rodlike particles are commonly
                      encountered in soft biological materials and their solidlike
                      response at extremely low volume fractions is also exploited
                      technologically. Understanding the link between the
                      physicochemical parameters such as size, aspect ratio,
                      volume fraction, and interparticle forces with the resulting
                      microstructure and the subsequent rheological response
                      remains challenging. In the present work, suspensions of
                      monodisperse rodlike virus particles, whose surface is
                      modified by grafting with a thermoreversible polymer
                      poly(N-isopropylacrylamide), are used as a model system. The
                      repulsive and attractive contributions to the total
                      interaction potential can be changed independently by
                      varying the ionic strength and the temperature. The effects
                      of these changes on the strength and structure of gels have
                      been studied near the gel transition using a combination of
                      rheological and scattering measurements. Rheological
                      measurements of the near critical gel properties as a
                      function of concentration and ionic strength proved to be
                      more sensitive compared to scattering in resolving the
                      structural differences. A percolating structure can be
                      formed at very low volume fractions, which show a weak
                      dependence on the ionic strength with the anisotropy of the
                      repulsive interactions playing the main role in creating
                      more "open" structures. The intrinsic stiffness of the
                      rodlike particles does not affect the moduli of the gel
                      states very strongly. (C) 2012 The Society of Rheology.
