Figure 5

The recorded kinetic curves when the PP:PPR coating was exposed to EGCg and oxidized EGCg solutions with various concentrations (A,E). The concentration dependence of the finally adsorbed amounts are shown separately (B,F). The biosensor signals recorded after cell addition onto the polyphenol exposed coatings. For comparison, the cell spreading curves recorded on the bare PP:PPR cell adhesive coating are also shown and all of the cell adhesion curves are normalized (C,G). The applied concentrations of EGCg and oxidized EGCg were 0, 0.05, 0.5, 5, 20, 40, 50, 500 μg/ml and indicated in the graphs. The concentration dependence of the normalized cell adhesion signals after 2 hours of cell addition (D,H).
