In this thesis, the structuring of different surfaces in xy- and in z-direction is described. Structuring in xy-direction was investigated on the example of peptide arrays, using a newly developed matrix material for the \u27solid\u27 solvent peptide array synthesis. Additionally, the Ugi four component reaction was investigated as a tool for peptide array functionalization. Structuring in z-direction was performed by molecular layer deposition of bifunctional molecules via Thiol-Ene chemistry
