Figure 2.
Contact angle measurements of PCL, NW, colPCL (col, collagen) and colNW surfaces. Experiments were replicated on at least five different samples (nmin = 5). Statistical significance was calculated using a one-way ANOVA with Tukey’s post hoc test. Results indicate significant differences between contact angles on all surfaces (*, #, @, p < 0.05). The contact angle on colNW surfaces could not be obtained.
