A Construction Scheme For A SET Device Based On Self‐Assembly Of DNA And Nanoparticles

The unique potential of molecular nanotechnology is based on the fabrication of materials and devices starting from molecular units. Comparable to and based on the synthetic approach in supramolecular chemistry or molecular biology, an extended toolbox of molecular units as well as tailored reactions is provided by these fields. On the other hand, the progress in synthesis of molecular structures is not directly transferable into technical applications, what is mainly due to a missing integration of the synthetic products into technological interfaces and environments. Self‐organization as used by nature to create complex organisms appears to be a solution to this dilemma. We propose a scheme for the realization of a single electron‐tunneling (SET) device based on this principle, and demonstrate the realization of various steps toward this aim, especially a technique for immobilizing exactly one DNA molecule in a microelectrode setup based on self‐assembly.
