Abstract

The ligand exchange process on gold nanorods (Au NRs) was explored by using laser desorption/ionization time-of-flight mass spectrometry (LDI-TOF-MS). Cetyltrimethylammonium bromide (CTAB) adsorbed on Au NRs was replaced with alkanethiol derivatives presenting different functional groups. The ligand exchange process was investigated under various conditions, such as in the presence of different functional groups in the ligands and with different concentrations of CTAB. The ligand-exchanged Au NRs were characterized by using a combination of UV-Vis spectroscopy and LDI-TOF-MS. Based on the results, it was revealed that LDI-TOF-MS analysis can provide crucial and distinct information about the degree of ligand exchange on Au NRs.

摘要

通过激光解吸/电离飞行时间质谱（LDI-TOF-MS）研究了金纳米棒（Au NRs）上的配体交换过程。吸附在Au NRs上的十六烷基三甲基溴化铵（CTAB）被具有不同官能团的链烷硫醇衍生物所取代。在各种条件下研究了配体交换过程，例如配体中存在不同官能团以及不同浓度的CTAB。通过紫外可见光谱和LDI-TOF-MS相结合的方法对配体交换后的Au NRs进行了表征。基于这些结果，揭示了LDI-TOF-MS分析可以提供有关Au NRs上配体交换程度的关键且独特的信息。
