Theoretical Analysis of an Amperometric Biosensor Based on Parallel Substrates Conversion

Figure 4

Normalized substrate concentration 𝑆_1𝑁 versus dimensionless space 𝑦 was computed using (11) for various values of reaction/diffusion parameter 𝛾_𝑆1, dimensionless parameter 𝛼 and for some fixed values of the parameters 𝛾_𝑆1, 𝛾_𝑆2, 𝛼, 𝛽. The key to the plot: (—) (11) and (∙ ∙∙) numerical simulation of (5).
