Patterned Production of Silver−Mesoporous Titania Nanocomposite Thin Films Using Lithography-Assisted Metal Reduction

A simple method that allows selective positioning of nanoparticles into mesoporous monolayer or multilayer thin films is presented. This technique applies UV lithography in order to bring about in situ light-induced reduction of silver in templated cavities of TiO<sub>2</sub>. The nanoparticle lithography presented here provides a novel approach to hierarchical lithography patterning for multifunctional devices.
