The subject-matter of the present work is the biofunctionalization of diamond thin films with active redox proteins to generate functional hybrid systems for bioelectronic applications. By means of a novel, radiation-induced biofunctionalization, an oriented and addressable protein immobilization as well as a good electronic coupling of the protein to the semiconductor surface was achieved. Investigations with the scanning tunneling microscope and coulometric measurements confirmed a high surface coverage of the immobilized protein. The electronic structure of the immobilized protein was determined by scanning tunneling spectroscopy. The radiation-induced modification of the self-assembled monolayer was characterized during the exposure to electrons and X-rays by a detailed spectroscopic analysis.
