SAMs
Surface engineering using self-assembled monolayers (SAMs) allows for the development of transparent, flexible, and easily applied nanocoatings. This technique enhances the properties of various materials, including metals, metal oxides, semiconductors, glass, and ceramics, even on complex surfaces like flat substrates, nanostructured surfaces, or powders.
SAMs are organic structures formed by the adsorption of specific molecules (in solution or gas phase) onto a substrate, where they spontaneously arrange into an ordered monolayer. By utilizing this technology, industries can improve durability, adhesion, and specialized functionality for applications in electronics, biomedical devices, coatings, and beyond.
Linkers
Self-assembled monolayers (SAMs) typically consist of bifunctional linkers with three key parts:
At SiKÉMIA, our catalog includes over 400 specialized linkers, covering silicon, phosphorus, sulfur, and carbon chemistries. Using this advanced surface modification technique, you can:
