| Outline of Final Research Achievements |
In this project, I developed a biosensing technology using "electrical detection of enzyme product by graphene transistor" and "encapsulation of reaction system in microdroplet". It is a first step of "Lab on a graphene", a novel platform for biosensing using graphene and resolves a problem derived from Debye screening. Enzyme urease was captured on graphene and its reaction product was successfully detected by graphene transistor. Also, pathogen was captured on graphene and detected by its reaction product. These results show my novel method can overcome the limitation of Debye screening and be applied to various kind of biosensing.
