Book Description
Self-assembled monolayers, form a dense assembly of organic molecules on various solid substrates and have caught strong attention due to their large number of potential applications in sensors, biochips, anti-fouling surface, organic electronics, optical devices, etc.. Silane- and thiol-containing molecules represent two classes of the most extensively investigated SAMs. Silane-based monolayers show good stability in their physical and chemical properties which allow them to be further functionalized by different surface chemical reactions or electrochemical oxidation lithography, while the simple and reproducible preparation procedure of thiol-containing SAMs attached to Ag/Au substrates motivates their use, e.g., as analytes in SERS applications. In this thesis, three different potential applications for SAMs were investigated to introduce surface chemical reactions on silane-based SAMs, to utilize surface modification by electrochemical oxidation lithography on OTS monolayers, and finally to investigate the stability of SERS substrates when being immersed into different solvents and buffer solutions utilizing 4-ATP as probe molecules.
