A novel strategy based on combined methods of Laser Interference Lithography and electrochemical anodization is developed for the fabrication of nanostructures.

As a proof of concept, the synthesis of long-range hexagonally ordered TiO₂ nanotube arrays is demonstrated.

TiO₂ nanotubes having 32 nm of inner diameter, around of 25 nm in wall thickness and 210 nm of lattice parameter were anodically grown under proper synthesis conditions.
