[资源] Advanced Materials最新综述---金纳米棒:合成、自组装和传感应用

最新一期的权威杂志Advanced Materials刊发了题为Functional Gold Nanorods: Synthesis, Self-Assembly, and Sensing Applications的综述文章,文章综述了纳米金的合成以及自组装的研究现状,并对金纳米棒在传感领域的应用。
文章31页,引文317篇。

Abstract
Gold nanorods have received much attention due to their unique optical and electronic properties which are dependent on their shape, size, and aspect ratio. This article covers in detail the synthesis, functionalization, self-assembly, and sensing applications of gold nanorods. The synthesis of three major types of rods is discussed: single-crystalline and pentahedrally-twinned rods, which are synthesized by wet chemistry methods, and polycrystalline rods, which are synthesized by templated deposition. Functionalization of these rods is usually necessary for their applications, but can often be problematic due to their surfactant coating. Thus, general strategies are provided for the covalent and noncovalent functionalization of gold nanorods. The review will then examine the significant progress that has been made in controllable assembly of nanorods into various arrangements. This assembly can have a large effect on measurable properties of rods, making it particularly applicable towards sensing of a variety of analytes. Other types of sensing not dependent on nanorod assembly, such as refractive-index based sensing, are also discussed.

我也在做金棒,做了已经三四个月了,但是反应后的溶液不是紫色就是红色,很少出现这么丰富这么鲜艳的色彩,另外颜色也很浅,清洗后也特别容易聚沉,在SEM下面观察可以发现好几层叠在一起,不知道该如何改进。不知道这么好的图片是怎么做出来的?
