Figure 8.

Cell viability and proliferation showing the absorbance at 570/600 nm (a) and the % viability (b) compared to the TCPS control on the functional polyester films on day 2, 4 and 7. A standard pattern in cell viability is present on day 2, which is also similar in days 4 and 7, except for the PE-Glyc80, which turns from statistically not significant, compared to the TCPS control on day 2, to statistically significant on days 4 and 7, clearly exceeding the TCPS control. Data are expressed as mean ± standard deviation. Asterisks denote statistical significance in viability for the functional polyesters compared to the TCPS control surface at each experimental time point (*: p < 0.05, **: p < 0.01, ***: p < 0.001, ns: not significant).
