dc.description.abstract | A mathematical model describing transport and kinetics of substrate and redox mediator within
chemically modified electrodes comprising of redox enzymes immobilized in dispersed carbon
nanotube meshes dispersed on support electrode surfaces is described. Two modes of amperometric
detection are subjected to analysis. In the first the current arising from re-oxidation of the reduced
mediator at the support electrode is measured, whereas in the second the current arising from reduction
of the oxidized mediator at the support surface is determined. Approximate analytical expressions for
the substrate reaction flux within the nanotube layer are developed and related to the measured flux at
the support surface. The kinetics both of substrate and mediator within the layer are also represented in
terms of a kinetic case diagram. | en |
