光与物质之间的相互作用可以通过在比感兴趣的波长短的长度尺度上构建材料来有效地控制。为了构建纳米级光学器件，等离子体学已经成为一门学科，在金属表面附近产生的电磁波的近场效应可以产生各种各样的新现象和迷人的应用。随着平面电子学的研究从光学和固态领域兴起，大多数实验室采用自上而下的光刻技术来实现他们的纳米光子设计。在这篇综述中，我们讨论了最近成功的利用自组装DNA纳米结构作为构建先进等离子体结构的支架的努力。DNA自组装利用了核酸序列的碱基配对特异性，允许有机分子的纳米级精确组织，也允许无机粒子在空间中的排列。因此，自底向上的自组装绕过了传统制造方法的许多限制。因此，像DNA折纸这样强大的工具已经突破了纳米光子学的界限，关于等离子体设计的新思路正在兴起。
The interaction between light and matter can be controlled efficiently by structuring materials at a length scale shorter than the wavelength of interest. With the goal to build optical devices that operate at the nanoscale, plasmonics has established itself as a discipline, where near-field effects of electromagnetic waves created in the vicinity of metallic surfaces can give rise to a variety of novel phenomena and fascinating applications. As research on plamonics has emerged from the optics and solid-state communities, most laboratories employ top-down lithography to implement their nanophotonic designs. In this review, we discuss the recent, successful efforts of employing self-assembled DNA nanostructures as scaffolds for creating advanced plasmonic architectures. DNA self-assembly exploits the base-pairing specificity of nucleic acid sequences and allows for the nanometer-precise organization of organic molecules but also for the arrangement of inorganic particles in space. Bottom-up self-assembly thus bypasses many of the limitations of conventional fabrication methods. As a consequence, powerful tools such as DNA origami have pushed the boundaries of nanophotonics and new ways of thinking about plasmonic designs are on the rise.
