What is a monolayer?

A monolayer is a single, continuous layer of molecules or atoms that are arranged in a two-dimensional structure. It can be formed from various materials, including organic compounds, metals, and biological membranes. Monolayers are significant in fields such as materials science, Nanotechnology, and Biology, as they affect properties like adhesion, wettability, and chemical reactivity. Their unique characteristics arise from the confinement of molecules to a single layer, influencing interactions at the molecular level.
