New ferromagnetic mesh electrode material for electroanalytical applications

A new, advanced, ferromagnetic carbon material (Fe@C NPs–GC 3D porous mesh) has been developed. The application of this electrode material has led to an increase in the voltammetric current density of paramagnetic species, such as FcTMA+, Fc-FcTMA+, on the application of a 140 mT magnetic field, compared with a glassy carbon electrode modified with a layer of Fe@C NPs alone. The functionality of the developed material was tested with two biologically important paramagnetic species: hemoglobin and dioxygen.
