The function of DNA during oxidative stress and its suitability as a potential building block for molecular devices depend on long-distance transfer of electrons and holes through the molecule, yet many conflicting measurements of the efficiency of this process have been reported. It is accepted that charges are transported over long distances through a multistep hopping reaction; this ‘G-hopping’ involves positive charges moving between guanines (Gs), the DNA bases with the lowest ionization… CONTINUE READING
