SAMstrukturen
SAMstrukturen, short for self-assembled monolayers, describe the structure of ultrathin organic films that form when molecules with a specific head group adsorb to a solid substrate and organize into a single, densely packed layer. These monolayers are used to modify surface properties such as wettability, chemical reactivity, and biocompatibility.
Formation and structure: In a typical process, molecules with a head group that forms a strong bond
Common chemistries and substrates: Alkanethiols on gold, organosilanes on oxide surfaces, and organophosphonates on metal oxides
Characterization and properties: Surface-sensitive techniques such as contact angle measurements, X-ray photoelectron spectroscopy (XPS), atomic force
Applications and limitations: SAMstrukturen are used for surface modification in biosensors, microfabrication, corrosion protection, and nano-organization.
