Understanding the Surface Chemistry of Thiolate-Protected Metallic Nanoparticles
Julio C. Azcárate,Gastón Corthey,Evangelina Laura Pensa,Carolina Vericat,Mariano H. Fonticelli,Roberto Carlos Salvarezza,Pilar Carro +6 more
TL;DR: In this article, the complexity of the thiol-metal NP interface chemistry and how this changes with the nature of the metallic core is discussed. And the most common strategy to protect these NPs is by using thiolate self-assembled monolayers, a strategy that has proved to be useful to control the physical and chemical properties of extended solid surfaces.
