摘要：

Electron transport through DNA occurs over very long distances (100 Angstrom 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.
