Production of nanowires by deposition of gold nanoparticles via flowstream technique onto a nanostructured polymer-coated substrate might offer a cheap and fast solution for industrial application [1]. We investigate the deposition of gold nanoparticles on colloidal polymeric samples with and without artificially induced µm-sized channels. Using a microfluidic cell in combination with in-situ GISAXS (beamline P03, Hamburg) we follow the gold deposition during the solution flow. First results indicate a different temporal nanoparticle layer growth compared to the three stages deposition on flat templates [2].
