Recent developments in the field of DNA nanotechnology have boosted techniques that allow to programmable self-assemble DNA into nanostructures with nanometer feature sizes and high a flexibility of achievable shapes. An efficient self-assembly of complex nanostructures from individual components in a bottom-up manner may be a less resource intensive fabrication method compared to top-down approaches in current micro- and nanofabrication. Here we review our attempts in using elaborate DNA templates as well as other self-assembly techniques to form inorganic nanostructures with optic and electronic functionality within a pure bottom-up procedure. Examples include plasmonic nanostructures, such as wave guides and antennas as well electrically conductive elements. In detail we will show how DNA can be used to form complex nano-scale molds that support casting of metal elements with DNA-encoded shapes as well as the formation of metal-semiconductor heterostructures.
