A simple and versatile light-based strategy to grow lowdimensional gold superstructures is presented; prolonged UVirradiation of TiO2 nanorod-stabilized Au nanoparticles in organic media promotes the progressive formation of distinctive chainlike metal assemblies, namely segments of a few gold particles, 2D or quasi-1D large structures composed of interlacing lines of hundreds of metal units over areas of abou 500 nm2
