Abstract:
This thesis provides a breakthrough in the construction of solid contact electrode (SCE) based on nanostructured carbon materials. It is checked the possibility of using single walled carbon nanotubes (SWCNTs) for the determination of ions in real complex samples such as plant sap. Additionally, the use of chemically modified graphene is performed as a transducer in solid state electrodes to determine the transduction mechanism. As a proof of concept two electrodes have been developed, in one hand, an ion-selective electrode (ISE) for the determination of calcium, and on the other one, an aptasensor for the selective detection of Staphylococcus aureus.
