Analytical Expressions for Steady-State Concentrations of Substrate and Oxidized and Reduced Mediator in an Amperometric Biosensor

Figure 2

Dimensionless concentration of (a) oxidized mediator 𝐹_O (17), (b) substrate 𝐹_S (13), and (c) reduced mediator 𝐹_R (14) versus normalized distance 𝜒 for 𝐵_O=0.5, 𝐵_S=0.0052, 𝜇_S=0.05, and 𝜙²_O=400. Solid lines represent the analytical solution whereas the dotted lines represent the numerical solution.
