摘要

成功地合成了链烷硫代金纳米粒子,其形成了自发有序的更大的纳米团簇。这些含有数千个以1,6 -己二硫醇功能化的金纳米颗粒的三维纳米团簇具有有趣的性质,并通过高分辨率透射电子显微镜(hrtem)、能量色散光谱、扫描电子显微镜和x射线光子光谱(XPS)对其进行了表征。这些结果对于进一步探索纳米团簇的电子特性以及了解硫醇在各种衬底(如玻璃和硅)上的化学吸附和物理吸附过程具有重要价值。

Synthesis And Characterisation Of Alkanethiolated Nanogold Clusters For Biomems Applications
Synthesis of alkanethiolated gold nanoparticles, which formed spontaneous ordering of larger nanoclusters, has been successfully demonstrated. These three-dimensional nanoclucters containing thousands of gold nanoparticles functionalized with 1, 6-hexanedithiol have interesting properties, which were characterized using High Resolution-Transmission Electron Microscopy (HR-TEM) coupled with Energy Dispersive Spectrometry, Scanning Electron Microscopy and X-ray Photon Spectroscopy (XPS). These results are valuable for further exploration into the nanoclusters' electronic characteristics as well as to understand the thiol chemisorption and physisorption processes onto various substrates such as glass and silicon.
