In this Master's thesis, we studied the self-assembly of a hydrophobin protein named HFBI and the possibility to use directed self-assembly with silicon patterned Si—SiO2 surfaces. The result was investigated using Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM). A clear contrast in protein adhesion and non-adhesion was observed between silicon and silicon dioxide areas, respectively. Additionally, a generic silicon template was designed and fabricated in order to enable electrical characterization of self-assembled hydrophobin monolayers in a controlled configuration setup. Electrical transport measurements were carried out on the final device at room temperature and at cryogenic temperatures (77 K and 4 K).
