In this work, we will highlight some of results from our work on the arrangement and characterization of functional DNA origami nanostructures for nanoelectronics. First, a new compelling approach to generate ordered arrays of DNA origami nanotubes on topographically patterned Si surfaces will be introduced. Then, the high-yield synthesis of high-density gold nanoparticle (AuNP) arrangements on DNA origami nanotubes with few unbound background nanoparticles will be presented. The high yield of AuNP assembly was achieved by careful control of the buffer concentration and the hybridization time on Si surface. Finally, also the assembly of heterogeneous nanostructures, i.e. 5 nm gold nanoparticles (AuNPs) and 10 nm semiconductor quantum dots (QDs), on a single DNA origami will be demonstrated.
