Research Abstract

Effects of DNA structure on the DNA-mediated electron transfer efficiency were quantitatively investigated using DNA containing novel photo-induced electron donors. It was suggested that local structural changes and electron affinities of DNA sequences as well as redox properties of the electron donors highly affect the electron transfer efficiency.
