Molecular Imaging Secondary Ion Mass Spectrometry for the Characterization of Patterned Self-assembled Monolayers on Silver and Gold
John G. Gillen, J. Bennett, Michael J. Tarlov, Donald R. Burgess Jr.
Self-assembly of alkanethiol monolayers on gold and silver substrates is a fast, easy, and convenient method for preparing stable organic films with well-defined physical and chemical properties that can be modified by changing the terminal functional group of the molecule. In this correspondence, we report on the use of secondary ion mass spectrometry (SIMS) for characterizing methods of producing micrometer spatial scale patterns of two chemically distinct monolayers on silver and gold surfaces. Production of these molecular patterns is the crucial first step toward the application of monolayer films for biosensor and microelectronic device fabrication
