General description
11-巯基十一烷酸（MUA）具有长链烷烃链和含羧基的硫醇，它们高度堆积并可形成自组装单层（SAM）。它可以修饰纳米颗粒的表面，以利于将其分散至基于水和溶剂的介质中。
Application
通过通常在生物医学应用中使用的Murray置换反应，MUA可用于1-十二烷硫醇保护的金纳米颗粒（AuNPs）的羧酸官能化。它也可通过创建具有高表面覆盖率的配体纳米组装体，来对铂纳米颗粒（PtNP）的表面进行修饰，从而用于表面增强拉曼光谱（SERS）分析。单细胞生物芯片平台可以利用细胞附着技术进行开发，其中MUA会形成附着至单细胞的SAM。MUA可用于制备四氟苯基活化的酯自组装单层膜，从而对胺修饰的寡核苷酸 和DNA进行固定化。 它还可用于为等离子生物传感器创建3D组装的金纳米结构。

Three-dimensional gold nanoarchitecture was fabricated by layer-by-layer (LbL) deposition of gold nanoparticles (AuNPs) and multiwalled carbon nanotubes (MWCNTs) on a glass substrate for a highly sensitive plasmonic biosensor using a conventional UV-vis instrument. Carboxyl-functionalized MWCNTs were reacted with 3-mercaptopropyltriethoxysilane (MPTES)
