Surface Modification
1-Undecanethiol is used to create well-ordered self-assembled monolayers (SAMs) on surfaces, particularly gold. These SAMs can be used to modify surface properties, such as wettability and adhesion.
Biomaterial Coatings
In biomaterials research, it is employed in mixed SAMs as spacers to provide a hydrophilic background, which helps in reducing non-specific protein adsorption and improving biocompatibility of surfaces.
Nanotechnology and Electronics
Its ability to form ordered monolayers makes it valuable in micro/nanoelectronics for fabricating precise structures and controlling surface interactions at the nanoscale.
Spacers in Mixed Monolayers
It functions as a spacer component in mixed SAM systems, allowing for the controlled presentation of other functional molecules or the creation of specific surface topographies.
