Biological properties of the samples. (a) Protein adsorption on different samples after immersion in α-MEM for 2 h. (b) RAW264.7 cell proliferation on the specimens after 1, 3, or 5 d of culture. Cell proliferation was measured by CCK-8. (c) After incubation for 2 h, RAW264.7 cells stained with DAPI. The scale bar represents 500 μm. (d) Initial adherent cell numbers at 1, 2, or 4 h. (e) After culturing for 2 d, the morphology of RAW264.7 cells on different samples was assessed by SEM images. The scale bar represents 5 μm. **p < 0.01 compared with the Ti group. At least three independent experiments were analysed, and the data are presented as the means ± SDs.
