In nature, DNA serves as the carrier of hereditary information. In contrast, the field of DNA nanotechnology employs DNA as building material for self-assembling nanoscopic objects [1]. The technique known as DNA origami introduced by Paul Rothemund in 2006 [2] opened up new routes for the assembly of nanoscale objects in space. This method uses hundreds of synthetic oligonucleotides to fold a long DNA single strand into arbitrary two-dimensional shapes and patterns. I will comment on recent advances of three-dimensional DNA origami [3] and some of its possible applications. In particular, I will describe the arrangement of nanoscale objects such as fluorophores [4] and nanoparticles with unprecedented precision.
