Embodiment 1
[0033] A preparation method of a biologically active material containing nano-calcium fluoride, comprising the steps of:
[0034] (1) Glycidyl methacrylate and triethylene glycol dimethacrylate are mixed at a mass ratio of 1:1, called BT, and then BT is mixed with camphorquinone and 4-(N,N-diethylamino ) ethyl benzoate is mixed, and the mass ratio of the three is 100:0.2:0.8 to obtain mixture A.
[0035] (2) Mix barium boroaluminosilicate glass particles with 3-(methacryloyloxy)propyltrimethoxysilane and n-n-propylamine in a mass ratio of 100:4:2, then stir with magnetic force Stir in a mixer at room temperature overnight until the liquid is clear and transparent to obtain mixture B.
[0036] (3) The bioactive material containing nano-calcium fluoride is obtained after mixing the nano-calcium fluoride with the mixture A and the mixture B, and the mass ratio of the three is 10:30:60.
[0037] (4) Molding the bioactive material prepared above: ①Use the lid of a sterile 96-well...
Embodiment 2
[0039] In step (3), the mass ratio of nano-calcium fluoride to mixture A and mixture B is 15:30:55, and all the other operations are the same as in Example 1.
Embodiment 3
[0041] In step (3), the mass ratio of nano-calcium fluoride to mixture A and mixture B is 20:30:50, and all the other operations are the same as in Example 1.
