Abstract: The first results of the bioimpedance technique application to thermo-destructive graphene-on-silicon-carbide will be presented as a basis for biosensor applications as well as the comparison to the CVD-grown graphene. Summary: The method of impedance measurements applied to graphene films expands the range of possibilities of using the material as sensitive biosensors.
* Monolayer graphene increases the sensitivity of measurements. Multilayer structures have greater reproducibility and multiplicity of use of sensors.
* Based on the results of comparative test tests, it is impossible to draw simple conclusions about the advantages of CVD or TDS graphene due to the inadequacy of the materials compared.
