| Outline of Final Research Achievements |
Biosensing applications based on large-scale, epitaxial graphene film on SiC substrate have been investigated. In the past decade, it have been considered that graphene devices, which were made from conventional mechanical exfoliation and chemical vapor deposition method, can detect solution pH. However, no one can explain why graphene devices can detect solution pH. By using the large-scale, epitaxial graphene film synthesized on a SiC substrate, the electrical characteristics were stable for pH changes. This results indicate that the epitaxial graphene film shows inherent sensing characteristics of graphene. Moreover, from the protein adsorption experiments to the epitaxial graphene film, the charge type of the protein (positive or negative) was independent on the electrical characteristics, indicating the charge transfer from the protein to the graphene film.
