{wiki=Self-assembled_monolayer}
A self-assembled monolayer (SAM) is a structured layer of molecules that spontaneously organizes into a single molecular layer on a substrate. This phenomenon occurs when amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, are placed in a solvent. The molecules align themselves in a specific orientation, forming a stable, ordered arrangement.
