Installing regular arrays on mesoscopic length scales plays an important role in nanotechnology. Different techniques of self-assembly via solvent evaporation out of dispersions have been used to obtain highly ordered colloidal structures [Roth]. We used Langmuir-Blodgett (LB) technique and spray deposition [Buffet], representing the most attractive tools for the formation of larger homogeneous colloidal arrays on any kind and shape of substrate. Due to their different deposition and boundary conditions, the assembly behaviour of polystyrene nanoparticles changes, resulting in two-dimensional layers with LB-technique and a large variety of pattern by spray deposition. We present our first results from atomic force microscopy and microbeam grazing incidence small-angle x-ray scattering (*GISAXS).
