Self-assembled Monolayers

Self-assembled monolayers (SAMs) are thin layers of molecules that organize themselves on surfaces, usually made of metals or semiconductors. Imagine tiny building blocks that attach themselves neatly and uniformly to a surface, creating a protective or functional layer. This process occurs spontaneously, meaning the molecules naturally arrange themselves without external help. SAMs are used in various applications, including improving corrosion resistance, enhancing the properties of sensors, and creating surfaces that can attract or repel specific substances. Their ability to modify surfaces at the molecular level plays a crucial role in modern technology and materials science.
