Hole and excess electron transfer dynamics in DNA

Abstract

Charge transfer in DNA attracts substantial attention from researchers in a wide group of fields such as bioscience, nanotechnology and physical chemistry. It is well known that both positive and negative charges, which are holes and excess electrons, respectively, contribute to the charge transfer in DNA. In the case of hole transfer in DNA, detailed mechanisms and dynamical parameters have been estimated by means of time-resolved spectroscopic methods and product analysis. On the other hand, detailed dynamics of excess electron transfer have not been established yet, although several aspects have been revealed by the continuous efforts of various research groups. In the present Perspective, studies on the charge transfer dynamics in DNA are summarized.
