Abstract

Light-responsive artificial ion channels are created using self-organized TiO₂ nanotubular arrays, whose ion transport properties can be regulated by external ultraviolet light. The formation of electrostatic traps within TiO₂ nanotubes by UV light contributes to the light-regulated ion transport.
