Optical Sensing of Attached Fibrinogen on Carbon Doped Titanium Surfaces

Table 2

Optical roughness (𝑅_opt) of the five studied surfaces with standard deviations at 𝐸_𝜆=1.959 eV immersed in background electrolyte in absence or presence of HPF molecules. Sample number indexes 𝑁_IF resemble those appearing in Figure 2.

Sample 𝑁IF	Absence of HPF molecules		Presence of HPF molecules
