Double-gate biosensor of glucose based on functionalized graphene
Malatinová, Michaela ; Pavlásková, Lucie (oponent) ; Bartošík, Miroslav (vedoucí práce)
This bachelor's thesis studies functionalization of graphene with linker molecule pyrenebutanoic acid succinimidyl ester and the enzyme glucose oxidase for glucose detection by a biosensor. The functionalized graphene implemented as the channel in field-effect transistor was used for the fabrication of the biosensing device. The functionalization process was confirmed by Raman spectroscopy and Atomic Force Microscopy. The characterization of the sensor and its qualities were monitored using transfer curves and time response. The shift in Dirac point and its position were inspected in relation to different concentrations of glucose and efficiency of the functionalization. The choice of the gate electrode of the graphene field-effect transistor was investigated with respect to its possible impact on the measurement results.
