"Controlled energy-transfer on a molecular scale is a goal in many areas of science, from artificial photosynthesis to molecular electronics. Now, DNA origami has been used to direct the transfer of energy from an excited input dye down one of two paths by precisely arranging a mediator dye.
(...) Irrespective of how this field will evolve in the future, the benefits from the high spatial resolution of DNA nanostructures will be essential. In that respect, the contribution from Tinnefeld and co-workers is very important."
