Photoinduced Electron Transport in DNA

Toward Electronic Devices Based on DNA Architecture
  • Hans-Achim Wagenknecht

Abstract

This chapter briefly summarizes important and basic aspects related to electron transport processes in DNA over long distances. Despite this broad knowledge, DNA research is still far from a profound and clear understanding of the electronic properties and electronic interactions in DNA that are crucial for any nanobiotechnological application. In the past, DNA-mediated charge transport has been a subject of considerable interest with biological relevance in the formation and repair of lesions and damage in DNA. The most recent developments underscore the significance of DNA or DNA-like architectures for the development of electronic devices on the nanoscale. It is clear that there is a great potential for applications of DNA-mediated charge transport processes in new DNA assays and microarrays for biotechnology, as well as DNA-inspired devices for nanotechnology.
