Abstract
We present a process for the phase-transfer of gold nanoparticles from an aqueous to an organic medium with normal alkanethiols. This method can be applied not only to large nanospheres (d~100 nm) but also to anisotropic nanoparticles like nanorods and nanoplates. It allows the comparison of the nanoparticle optical properties when they are dispersed in both aqueous and organic media.
摘要
我们提出了一种从水相向有机相转移金纳米粒子的相转移方法，使用的试剂是正构硫醇。该方法不仅适用于大的纳米球（直径~100nm），也适用于纳米棒和纳米片等各向异性纳米粒子。该方法可用于比较纳米粒子在水相和有机相中的分散状态下的光学性质。
