We can synthesize various component molecules in which predesigned structures are specifically coded with the rules necessary for the molecular assembly. This looks as if hiomolecules in nature, such as DNAs or proteins, are coded by the structural specificity to express their functions. In the case of an alkanethiol-hased SAM, the code is set in two structural parts, that is, a thiol substituent and an alkane chain. The thiol substituent is a soft binder effective to specific surfaces, such as gold, to which the component molecules can be chemically adsorbed from the solution or gas phase [5]. The alkane chain is a building block to form a monolayer and can serve as the structural unit that enables the spontaneous organization of the tightly packed mono-layer through van der Waals interaction (or hydrophobic interaction in water) between the alkane chains. A schematic of alkanethiol-based SAM structure is shown in Fig. 1 [1].
