DNA self‐assembly is a powerful tool to arrange optically active components with high accuracy in a large parallel manner. A facile approach to assemble plasmonic antennas consisting of two metallic nanoparticles (40 nm) with a single colloidal quantum dot positioned at the hot spot is presented here. The design approach is based on DNA complementarity, stoichiometry, and steric hindrance principles...
Ideal dimers comprising gold nanoparticles with a smooth surface and high sphericity are synthesized by a substrate‐based assembly strategy with efficient cetyltrimethylammonium bromide removal. An unprecedented structural and plasmonic uniformity at the single‐particle level is observed since inhomogeneities resulting from variations in gap morphology are eliminated. Single ideal dimers are analyzed...
In article number 1702754, Sebastian Schlücker and co‐workers synthesize ideal gold dimers of two spherical gold nanoparticles with a controlled gap distance and gap morphology. While theoreticians have been able to describe the properties of such a model system, experimentalists have failed to synthesize it. Here, elastic scattering of an ideal gold dimer using white light together with an electron...
