The engineering of the optical and plasmonic properties of metallic nanostructure is one of the key ingredients for the complete control of materials at the nanoscale. Here we show how it is possible to control the plasmonic resonance of complex architectures of gold nanoparticles using the peculiar properties of DNA Watson and Crick pairing rules. In this chapter, we will first introduce all the steps required to generate, purify, and characterize DNA nanostructures, then we will guide the reader to the main steps required to decorate them with a precise amount of gold nanoparticles and, finally, we will describe the main approach used to characterize their plasmonic response.
金属纳米结构的光学和等离子体特性工程是在纳米尺度上完全控制材料的关键要素之一。在这里，我们展示了如何利用DNA沃森和克里克配对规则的特殊性质来控制金纳米颗粒复杂结构的等离子体共振。在本章中，我们将首先介绍生成、纯化和表征DNA纳米结构所需的所有步骤，然后引导读者了解用精确数量的金纳米颗粒修饰它们所需的主要步骤，最后，我们将描述用于表征其等离子体响应的主要方法。
