摘要

金纳米粒子(AuNPs)具有优异的等离子特性,包括颜色鲜艳,能产生局部电场、热载流子和热量。这些特性被广泛应用于生物学、传感、光谱学、催化和医学领域。更吸引人的是,当 AuNPs 组装在一起并在颗粒之间形成纳米间隙时,这些特性会大大增强。因此,以可控方式组装 AuNPs 是研究和应用等离子特性的关键步骤。在本报告中,我将介绍我的研究小组十年来为开发最佳组装方法所付出的集体努力。我将详细描述组装过程,并演示该方法产生的各种纳米组装体。通过受控组装,我们可以系统地研究纳米缝隙的等离子特性与结构参数之间的关系。在众多特性中,我重点关注等离子体耦合。最后,我将讨论纳米组装等离子体学的前景。

Controlled assembly of gold nanoparticles: Methods and plasmon coupling properties

Controlled assembly of gold nanoparticles: Methods and plasmon coupling properties

Gold nanoparticles (AuNPs) exhibit excellent plasmonic properties, including bright color and generation of localized electric field, hot carriers, and heat. These properties are widely applied in biology, sensing, spectroscopy, catalysis, and medicine. More attractive is that these properties are tremendously enhanced when AuNPs are assembled and form nanogaps between the particles. Therefore, assembling AuNPs in a controlled fashion is a key step for the study and applications of plasmonic properties. In this Account, I will introduce my group's collective efforts that have been made for a decade to develop the best assembly method. I will describe the assembly procedure in detail and demonstrate the various nanoassemblies produced by the method. The controlled assembly allows us to systematically examine the relationship between the plasmonic properties and structural parameters of the nanogaps. Among many properties, I focus on plasmon coupling. To conclude, I will discuss the prospects of nanoassembly plasmonics.
