AB  - 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].
