Definition
Self-assembled monolayers (SAMs) are a self-organizing layer of amphiphilic molecules in which the hydrophillic "head" group is attracted to a substrate and the hydrophobic "tail" end sticks-out into the solution with a functional molecule on the end. The self-attracting head group will nucleate and grow into a tightly packed single molecule layer on the substrate.
