Graphene as a sensor material

This thesis is concerned with the synthesis, characterization, and utilization of (reduced) graphene oxide (i.e. chemically derived graphene) for sensor applications. It discusses several proof of principle and analytical concepts based on different graphene materials. These concepts point out the chemically derived variants as extremely valuable materials for sensor applications due to their excellent features.
Since the materials themselves were only superficially examined before, a detailed investigation is performed. The results reveal that these materials are indeed very complex, heterogeneous entities. Also, the potential for novel sensor concepts is exhibited. Synthesis mechanisms are developed, which expose the complex chemistry behind the simple preparation.
Finally, sensor concepts developed during this work are presented. In particular, the basic principles behind a gas sensor for NO2, and an affinity sensor based on surface plasmon resonance for amines are described.
