3. Results 3.1. Influence of Ligand Coating on Surface Properties of PGDThe water contact angles determined on the uncoated PGD and TCP were approximately 60° (Figure 2a). The surface wettability of the PGD surfaces was significantly enhanced after coating with saturated Col I and HyA, while the Col I-coated PGD was the most hydrophilic. The surface morphology of uncoated and coated PGD was examined by scanning electron microscope (SEM).
