Abstract
Here we report an example of a mixed thiol monolayer on the surface of Ag nanoparticles which promotes adsorption and quantitative SERS detection of 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy"); the thiols in the mixed monolayers act synergistically since MDMA does not adsorb onto colloids modified with either of the thiols separately.
摘要
在这里，我们报告了一个在 Ag 纳米粒子表面上的混合硫醇单层的例子，该单层促进了 3,4-亚甲二氧基甲基苯丙胺（MDMA，“摇头丸”）的吸附和定量 SERS 检测；由于 MDMA 不会吸附到分别用两种硫醇修饰的胶体上，所以混合单层中的硫醇具有协同作用。
