Self-assembled monolayers (SAMs) are well-defined and ordered films of molecules that are spontaneously deposited on a surface. By designing molecules with desired head groups for binding specific surfaces, such SAMs can be interesting for a lot of applications such as molecular electronics and biosensors. In this study, SAMs of organic and biological molecules have been investigated. SAMs of thiophenol, a newly designed Schiff base (E)-4-((4-(phenylethynyl)benzylidene)amino)benzenethiol molecule, a newly designed 4-(4,7-di(thiophen-2-yl)-1H-benzo[d]imidazol-2-yl)benzaldehyde monomer were studied. Mixed SAMs of biotin and streptavidin and graphite binding peptide assemblies are also studied. SAMs were prepared by solution phase method. The gold surface and graphite surface were used as a substrate, because they are both chemically inert to oxidation and flat surfaces. Scanning Tunneling Microscope (STM) was the main experimental technique used here. It was used to obtain images of SAMs at an atomic scale. Scanning Tunneling Spectroscopy (STS) was used to provide information about the local density of states of molecules. Spectroscopic Ellipsometry (SE) was used to measure the monolayer thickness. Contact Angle Measurements was used to determine the surface wettability. X-Ray Photoelectron Spectroscopy (XPS) was used to analyze surface chemistry of SAMs. Surface-Enhanced Raman Spectroscopy (SERS) was used to identify the molecules on a surface.
