[0037] Figure 1 It is a bar chart showing the promotion of cell proliferation by the bioactive material with both anti-inflammatory and repair functions prepared in Example 1 of the present invention. The blank group uses the well plate as a control.

[0038] Figure 2 It is the absorbance value of the bioactive material with both anti-inflammatory and repair functions prepared in Example 2 of the present invention for scavenging reactive oxygen species. DPPH (1,1-diphenyl-2-picrylhydrazyl radical) is a free radical widely used to evaluate antioxidant activity. Its ethanol solution is dark purple, has a strong absorption at 517 nm, and is relatively stable. When the lone pair electrons of the DPPH free radical are paired, the solution color becomes lighter and the absorbance value decreases. The change in the absorbance value is proportional to the ability of the bioactive material to scavenge free radicals. By measuring the change in the absorbance value, the scavenging rate of the bioactive material for DPPH free radicals can be calculated, thereby evaluating its ability to scavenge reactive oxygen species. At 517 nm, the absorbance of the model group (DPPH pure reagent group) in the figure is 0.903, while that of the experimental group (the material prepared in Example 2) is 0.266. It can be seen that the experimental group has excellent ability to scavenge reactive oxygen species.

[0039] Figure 3 It is a physical picture of the bioactive material with both anti-inflammatory and repair functions prepared in Example 2 of the present invention for scavenging reactive oxygen species ((a) is the model group, (b) is the experimental group, and from left to right in (b) are Comparative Example 1, Example 2, and Comparative Example 2). Without scavenging reactive oxygen species, it shows a deeper color. When it has the function of removing reactive oxygen species, the solution color turns light yellow. It can be seen that the experimental group has excellent ability to scavenge reactive oxygen species. Although Comparative Example 1 has excellent ability to scavenge reactive oxygen species, due to the excessive addition of cerium oxide, its cytotoxicity is relatively large; the ability of Comparative Example 2 to scavenge reactive oxygen species is significantly worse than that of Example 2.
