Abstract: We have developed an integrated technology that allows patterning and formation of gold-nanoparticles in self-assembled mesoporous films in single step; this technique allows fabrication of patterned structures with high aspect ratios in a direct, simple, and reproducible way. We have used high intensity X-ray that interact with the mesoporous matrix through dfferent processes, by removing the organic templates, increasing the polycondensation of thhe organic-inorganic silica network, and partially removing the methyl groups bonded in the hybrid matrix. The final material, after patterning and chemical etching, exhibits gold nanoparticles of few nanometers homogeneously dispersed in thhe porous matrix.
