The spray-drying of aerosol droplets is an economically attractive method to obtain mesostructured nanoparticles. Undestanding the self assembly process during the precursors condensation is the key to control the size and the architecture of the nanoparticles, which can be subsequently used for many different applications, i.e. as hollow delivery vehicles for drugs, or for catalysis. In this communication, the in-situ characterization with SAXS of the formation and organization of mesostructured silica nanoparticles synthesized in the gas phase will be presented. Different precursors solutions were tested, and the effect of increasing temperatures and humidity conditions during the evaporation process will be shown.
