Self-assembled monolayers and nanoparticles

Section 12.09.6 details recent advances toward the application of organometallic receptors as sensing devices, including their use in dendrimer, polymer, functionalized nanoparticle, and self-assembled monolayer systems.

Nanoparticle-based corrosion inhibitors and self-assembled monolayers... 

Gold electrodes coated by nanostructured self-assembled monolayer of TMPP and Cl2 are used as template for in situ synthesis of metallic nanoparticles (Figure 2). 

This bulky ligand has two thiols to produce small Au nanoparticles. Figure 5 presents the TEM images of self-assembled monolayers of 1.5nm TCgBIP- and 1.6nm TCsBIP-protected Au nanoparticles at the air-water interface. 

For transition and precious metals, thiols have been successfully employed as the stabilizing reagent (capping reagent) of metal nanoparticles [6]. In such cases, various functionalities can be added to the particles and the obtained nanoparticles may be very unique. It is well known that thiols provide good self-assembled monolayers (SAM) on various metal surfaces. When this SAM technique is applied to the nanoparticle preparation, nanoparticles can be covered constantly by functionalized moieties, which are connected to the terminal of thiol compounds.
