Effects of Duplex Stability on Charge-Transfer Efficiency within DNA,d pyrimidine bases and minor 5-methylcytosine in aerated aqueous solutions. Information is also provided on the final one-electron oxidation products of 8-oxo-7,8-dihydroguanine, an ubiquitous decomposition product of DNA with most chemical and physical oxidizing agents, that exhibits a low ionizati

Hole Injection and Hole Transfer through DNA: The Hopping Mechanism,a carbohydrate radical cation whose precursor is site-selectively incorporated into the DNA. For the charge injection step the influence of the distance, the energy difference of donor and acceptor, and the bridge were measured. The guanine radical cation, generated in the injection step, triggered

Dynamics and Equilibrium for Single Step Hole Transport Processes in Duplex DNA,arated by one or two A:T base pairs have been investigated by means of nanosecond time-resolved absorption spectroscopy with kinetic modeling. Photoinduced electron transfer from G to a stilbenedicarboxamide (Sa) hairpin linker is used to generate a G./Sa. radical ion pair separated by two or three

Hole Injection and Hole Transfer through DNA: The Hopping Mechanism, distances in a multistep hopping process. Trapping of the positive charge at the DNA bases either by nucleophilic attack or by proton transfer to the surrounding water stops the hole transfer through DNA. This can be induced, for example, by mismatches of the G:C base pairs.

DNA-Mediated Charge Transport Chemistry and Biology,igned that detect, with high sensitivity, single base mismatches in DNA, as well as protein-dependent changes in DNA stacking. How proteins modulate long-range DNA charge transport has also been examined, and, in exploring charge transport within the biological milieu, oxidative damage to DNA within the cell nucleus is being probed.
