DNA-origami is a wonderful technique that enables the fabrications of all kinds of nanoscopic objects. We have been using them to build nanophotonic devices combining metallic nanoparticles to form optical antennas and single molecules.
In our recent paper in Nano Letters, we demonstrate how optical nano-antennas self-assembled using DNA-origami can be used to direct the fluorescence emission of freely rotating molecules.
This work is part of our standing and fun collaboration with the groups of Prof. Dr. Philip Tinnefeld (LMU Munich) and Prof. Guillermo Acuna (Uni Fribourg, Switzerland).
