金属纳米结构表现出特殊的光学共振模式，起源于材料中导电电子的亚波长限制。这些共振模式因其在光学和传感应用中的应用潜力而成为研究的热点。在这篇简短的综述中，重点介绍了我们小组在这一领域的最新成就。介绍了一种先进的金属纳米结构的湿化学合成方法，并展示了其在电场作用下的精确定位和操控。接下来，将在几个例子中描述这些纳米结构在小分子检测中的应用。此外，还将展示金属纳米结构可用于亚波长光聚焦和有效地将能量耦合到高分子链中。
Metal nanostructures exhibit special optical resonance modes originating from the subwavelength confinement of conductive electrons in the material. These resonance modes represent a strong research focus due to their application potential in optics and sensing application. In this short review recent achievements of our group in this field are highlighted. A wet-chemistry approach synthesis of advanced metallic nanostructures will be introduced and their exact positioning and manipulation by electric field is shown. Next, the application of these nanostructures for a detection of small molecules will be described in several examples. Also, it will be shown that metal nanostructures can be used for sub-wavelength light focusing and for efficient energy coupling into polymer chains.
