Strands of gold: Extended one-dimensional arrays of gold nanoparticles up to 4 μm long can be assembled by hybridization between thiolated DNA/nanoparticle 1:1 conjugates and long DNA templates, which were prepared by rolling-circle polymerization (see picture). The linear self-assembled structures could link the nanometric properties of materials with the convenience of micrometric manipulation.
