| Research Abstract |
Biosensing applications based on graphene field-effect transistors were investigated. Solution pH can be detected with the resolution of 0. 025 using the graphene devices. Although the antibodies cannot be used for FET-based biosensors due to the thickness of the electrical double layer, we applied the aptamer and fragment antigen-binding. The results show that the graphene field-effect transistors have high potentials for the biosensors.
