(A) Schematic illustration of the programmable directional assembly of NCs in a DNA template. (B) Sketch of the DNA origami and two Au NCs to assemble the optical nanoantenna (left), and its numerical simulation of the electric field intensity (right). (C) Single-molecule fluorescence transient response for the dimer nanoantenna (black line) or the DNA origami without NCs (red line) at ten times excitation intensity.
