      abstract     = {We employed evanescent wave dynamic light scattering [1] to
                      study thenear wall dynamics of different types of silica
                      particles, i. e. full spheres,spherical shells and spheres
                      with surface roughness, with the objective toinvestigate the
                      effect of particle morphology on their near wall
                      dynamics.While the dynamics of spherical particles and
                      hollow shells is inagreement with theoretical predictions
                      for hard sphere colloids [2] withinexperimental error, the
                      rough particles show slower dynamics thanexpected for
                      spheres. As the latter finding is at conflict
                      withhydrodynamic theory, we further investigated the
                      influence of staticparticle wall interaction on the
                      dynamics. Our results indicate that therough particles
                      experience stronger van der Waals attraction thanparticles
                      with a smooth surface, which may contribute to settle an
                      openquestion in literature concerning the effect of particle
                      roughness oninteraction and adhesion [3-4].},
