      abstract     = {In this article we report on the synthesis and
                      characterization of a system of colloidal spheres suspended
                      in an aqueous solvent which can be refractive index-matched,
                      thus allowing for investigations of the particle near-wall
                      dynamics by evanescent wave dynamic light scattering at
                      concentrations up to the isotropic to ordered transition and
                      beyond. The particles are synthesized by copolymerization of
                      a fluorinated acrylic ester monomer with a
                      polyethylene-glycol (PEG) oligomer by surfactant free
                      emulsion polymerization. Static and dynamic light scattering
                      experiments in combination with cryo transmission electron
                      microscopy reveal that the particles have a core shell
                      structure with a significant enrichment of the PEG chains on
                      the particles surface. In index-matching DMSO/water
                      suspensions the particles arrange in an ordered phase at
                      volume fraction above $7\%,$ if no additional electrolyte is
                      present. The near-wall dynamics at low volume fraction are
                      quantitatively described by the combination of electrostatic
                      repulsion and hydrodynamic interaction between the particles
                      and the wall. At volume fractions close to the isotropic to
                      ordered transition, the near-wall dynamics are more complex
                      and qualitatively reminiscent of the behaviour which was
                      observed in hard sphere suspensions at high concentrations.},
