Modeling of Label-Free Optical Waveguide Biosensors with Surfaces Covered Partially by Vertically Homogeneous and Inhomogeneous Films

Figure 4

The quasihomogeneous adlayer film thickness in function of the surface coverage for seven adlayer film thicknesses. For thicker layer thicknesses—100 nm, 200 nm, and 500 nm—overrated values and singularities appeared in case of the OW2400 and the reverse chip. The singularities are shown in the insets.
