Inexpensive synthesis of custom DNA sequences has enabled the design of nanoscale structures that self-assemble with high yield [1] and high precision. Traditional “top-down” fabrication techniques, such as electron beam lithography, require costly equipment and are unsuitable for high-volume manufacturing due to limited throughput. To demonstrate the flexibility of DNA-based nanoscale structures, we designed and synthesized the Boise State “B” using 169 unique strands of DNA (Fig. 1a). Building on this success, we synthesized DNA crystals (Fig. 1b) [3] as scaffolds for the self-assembly of split ring resonators (SRRs – Fig. 1c,d). SRRs are gapped, conducting rings with negative permeability [2]. Potential applications of split ring resonators include enhanced medical imaging, “super lenses” that can operate below the diffraction limit, and energy efficient interconnects for semiconductors [4]. Here we describe the design and experimental progress in array synthesis and characterization.
