Cover Picture: Single-Molecule Fluorescence Studies Reveal Long-Range Electron-Transfer Dynamics Through Double-Stranded DNA (ChemPhysChem 4/2009)
The cover picture shows the results of single-molecule experiments where fluctuations in the fluorescence emission of a FRET donor could be related to charge transfer through the π-stack of double-stranded DNA. The bottom drawing shows a microscopic single-molecule image of individual DNA probes depicted as green and red spots, indicative of donor and acceptor emission respectively. The overlay on the right is a sketch of a DNA probe with combined electron and energy transfer. The first second of the fluorescence transient shown on top is indicative of energy transfer until the acceptor photo-bleaches (red). On page 629, M. Kumbhakar, D.-P. Herten et al. demonstrate that the donor emission shows fluctuations (green) after acceptor bleaching that can be related to charge transfer between donors and acceptors transmitted by the π-stack of double-stranded DNA.
