Self-assembly of DNA into nanoscale three-dimensional shapes

An important goal in nanotechnology is the programmable self-assembly of complex, three-dimensional nanostructures. With DNA as the building block, synthesis techniques have developed to the stage where two-dimensional designer structures and certain three-dimensional structures can be produced. Douglas et al. describe a refinement of the scaffolded DNA origami technique capable of producing three-dimensional objects of more or less any desired...
