Abstract

In this study, we investigated use of local surface plasmon resonance (LSPR) of metal nanoparticles (NPs) as a correlative light and electron microscopy (CLEM) tag for biological samples. Gold NPs in ultra-thin sections for TEM revealed that LSPR could be observed by optical microscopy at sizes of 20 nm or larger. Gold NPs at sizes less than 20 nm could be observed using the gold enhancement method. Therefore, this CLEM tag could be applied to immunoelectron microscopy using this gold enhancement method.

金纳米粒子的局部表面等离子体共振作为生物样品的相关光学和电子显微镜(CLEM)标签。

在本研究中，我们研究了金属纳米颗粒（NP）的局部表面等离子体共振（LSPR）作为生物样品的相关光学和电子显微镜（CLEM）标签的使用。用于TEM的超薄切片中的金NP显示，可以通过光学显微镜在20nm或更大的尺寸下观察到LSPR。使用金增强方法可以观察到尺寸小于20nm的金NP。因此，这种CLEM标签可以应用于使用这种金增强方法的免疫电子显微镜。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
