Self-Assembly Materials

Molecular self-assembly1 is the assembly of molecules without guidance or management from an outside source. Self-assembly can occur spontaneously in nature. One such example is the self-assembly of the lipid bilayer membrane in cells.

An efficent approach to molecular self-assembly having received ample attention during the last decade is the creation of self-assembled monolayers (SAMs) using relatively weak intermolecular interactions between certain types of organic molecules, such as thiols or phosphonic acids, and a gold or oxidic surface.

SAMs have a wide range of applications including surface wetting, non-fouling property, electrochemistry, surface passivation, protein binding, DNA assembly, corrosion resistance, biological arrays and cell interactions.2-4 SAMs also are contained, in large numbers, in materials for the semiconductor electronics industry such as nanowires, nanotransistors and nanosensors.
