Electron spin resonance (ESR) has emerged as a powerful spectroscopic technique to study the properties of metal nanoparticles (NPs) protected by a self-assembled monolayer (SAM) of organic molecules. This technique has been employed to explore the capacity of homoligand monolayers to bind to a hydrophobic probe or to "sense" the hydrophobicity of mixed-ligand monolayers. Moreover, spin labels anchored to the metal surface enable the investigation of the dynamic of the ligands that form the monolayer. Here we review these applications with the aim of unravelling the many features of monolayer-protected metal NPs.
电子自旋共振（ESR）已成为一种强大的光谱技术，可用于研究受有机分子自组装单层（SAM）保护的金属纳米粒子（NPs）的性质。该技术已被用于探索同配体单层与疏水性探针结合的能力，或“感知”混合配体单层的疏水性。此外，固定在金属表面的自旋标记物可用于研究形成单层的配体的动态。在这里，我们回顾了这些应用，旨在揭示单层保护的金属 NPs 的许多特性。
