DNA as a Supramolecule for Long-Distance Charge Transport

Abstract

Electron transport through DNA occurs over very long distances (100 Å and more). The process follows a hopping mechanism and depends upon the DNA sequence. The efficiency of the charge transport is only slightly distance dependent because in most cases the H₂O trapping of the charge is slower than the electron transfer. These findings show the potential of substituted DNAs as new materials for nanoelectronics in the future.
