      abstract     = {Over the last decade we developed instrumental equipment,
                      based onevanescent light scattering, to investigate the
                      static interaction of colloidalparticles with an adjacent
                      wall, as well as the near wall dynamics of theseparticles.
                      In this talk I will give an introduction to the techniques,
                      beforediscussing recent experiments.Using Total internal
                      Reflection Microscopy (TIRM), we investigated thedepletion
                      interaction induced by rod– and disc– shaped particles
                      at rest andunder the influence of flow fields. There we
                      could show that the strength ofthese depletion potentials
                      can be tuned by the applied shear rate.Using Evanescent Wave
                      Dynamic Light Scattering (EWDLS) we studied thedynamics of
                      particles close to a flat interface, providing experimental
                      prove forthe long standing theoretical prediction that
                      particle dynamics near walls areslowed down and are
                      anisotropic. For the first time, we showed thatrotational
                      and translational contributions to the particles near wall
                      dynamicscan be separated experimentally.},
