Photocatalytic lithography with image inversion

The feasibility of the inversion of metal images obtained by the chemical deposition of nickel onto Pd²⁺-loaded films of nanostructural TiO₂ exposed to high irradiation doses has been demonstrated. This permits the generation of both negative and positive metallic pictures by varying the irradiation dose, which expands the scope for obtaining planar metallic elements with complex structural organization.
