Chiroplasmonic properties of nanoparticles, organized using DNA-based nanostructures, have attracted both theoretical and experimental interest. Theory suggests that the circular dichroism spectra accompanying chiroplasmonic nanoparticle assemblies are controlled by the sizes, shapes, geometries and interparticle distances of the nanoparticles. In this Review, we present different methods to assemble chiroplasmonic nanoparticle or nanorod systems using DNA scaffolds, and we discuss the operations of dynamically reconfigurable chiroplasmonic nanostructures. The chiroplasmonic properties of the different systems are characterized by circular dichroism and further supported by high-resolution transmission electron microscopy or cryo-transmission electron microscopy imaging and theoretical modelling. We also outline the applications of chiroplasmonic assemblies, including their use as DNA-sensing platforms and as functional systems for information processing and storage. Finally, future perspectives in applying chiroplasmonic nanoparticles as waveguides for selective information transfer and their use as ensembles for chiroselective synthesis are discussed. Specifically, we highlight the upscaling of the systems to device-like configurations.

基于等离子DNA的纳米结构

使用基于DNA的纳米结构组织的纳米粒子的等离子性质吸引了理论和实验兴趣。理论表明,伴随着手性等离子体纳米颗粒组装体的圆二色性光谱受纳米颗粒的大小,形状,几何形状和颗粒间距离控制。在这篇综述中,我们提出了使用DNA支架组装手性等离子体纳米颗粒或纳米棒系统的不同方法,并且我们讨论了动态可重构的手性等离子体纳米结构的操作。不同系统的等离子特性以圆二色性为特征,并由高分辨率透射电子显微镜或低温透射电子显微镜成像和理论建模进一步支持。我们还将概述手性等离子体组件的应用,包括将其用作DNA传感平台以及信息处理和存储的功能系统。最后,讨论了将手性等离子体纳米粒子用作选择性信息传递的波导及其在手性选择性合成中的应用的未来前景。具体来说,我们重点介绍了将系统升级为类似设备的配置。
