October 1, 2013 – DNA origami templated self-assembly has shown its potential in creating rationally designed nanophotonic devices in a parallel and repeatable manner. In this investigation, we employ a multiscaffold DNA origami approach to fabricate linear waveguides of 10 nm diameter gold nanoparticles. This approach provides independent control over nanoparticle separation and spatial arrangement. The waveguides were characterized using far-field polarization spectroscopy and the group’s suite of Bruker atomic force microscopes in the Surface Science Laboratory. This work provides a path toward large-scale plasmonic circuitry.
