      abstract     = {Whensuspended colloidal particles move in the ultimate
                      vicinity of a flat solid interface, their mobility is
                      smaller than in the bulksuspension due to a drag force
                      caused by hydrodynamic interaction between the particle and
                      the wall. Further, the friction acting on aparticle depends
                      on the direction of motion. Leading to different diffusion
                      coefficients parallel, 𝑫∥,and normal, 𝑫 to the
                      interface. Toexpand the catalogue of particles being studied
                      at interfaces [1-5], we are now investigating colloidal
                      particles with controlled surfaceroughness and hollow
                      shells. In this work, we show the anisotropic diffusion of
                      these particles when they are close to a
                      glass/dispersioninterface by means of evanescent wave
                      dynamic light scattering (EWDLS). By comparing the results
                      from various kinds of particles withdata from smooth
                      spherical particles and with theoretical predictions for
                      hard sphere colloids [4], we assess the influence of
                      particlemorphology on the particle interface hydrodynamic
                      interaction},
