Optical antennas have been widely used for manipulating light-matter interactions at the nanoscale in order control the emission intensity and directivity of single molecules. However, to date, precisely controlling the interaction between molecules and antennas at the single level is still challenging. In this contribution, we exploit the DNA origami technique to self-assemble ultra-compact antennas based on two gold nanorods using a T-shaped host structure. These antennas are capable of directing the emission of single fluorophores placed in vicinity of the tip of one nanorod with nm precision.
