Embodiment 1
[0044] This embodiment provides a method for constructing a silk fibroin / silver phosphate nanowire composite pore scaffold, which includes the following steps:
[0045] First prepare a silk fibroin-silver nitrate mixed solution, where the concentration of silk fibroin is 4%, the concentration of silver nitrate is 2%, and the mass ratio of silk fibroin to silver nitrate is 2:1. See the picture of the mixed solution figure 1 ;
[0046] Pour the mixed solution into a mold placed horizontally on a metal plate at -15°C. After fully freezing, transfer the obtained ice cubes to a freeze dryer for drying. After the ice crystals sublimate, the white porous solid obtained is silk fibroin. Protein-oriented channel scaffold, freezing temperature affects the pore size, see the photo of the oriented channel scaffold figure 2 ;
[0047] The above-mentioned oriented porous scaffold is placed in a phosphoric acid solution with a surfactant PAA concentration of 0.2 mg / ml, wherein the phosphoric acid ...
Embodiment 2
[0056] This embodiment provides a method for constructing a silk fibroin / silver phosphate nanowire composite pore scaffold, which includes the following steps:
[0057] Prepare a silk fibroin-silver nitrate mixed solution, where the silk fibroin concentration is 4%, the silver nitrate concentration is 4%, and the mass ratio of silk fibroin to silver nitrate is 1:1;
[0058] Pour the mixed solution into a mold placed horizontally on a metal plate at -5°C. After fully freezing, transfer the obtained ice cubes to a freeze dryer for drying. After the ice crystals sublimate, the white porous solid obtained is silk fibroin. Protein-oriented channel scaffold;
[0059] The above-mentioned oriented porous scaffold is placed in a phosphoric acid solution with a surfactant PAA concentration of 0.25 mg / ml. The phosphoric acid solution uses a mixture of methanol and water as the solvent, and the mass ratio of methanol to water is 90:10. The mass volume ratio concentration is 2.6mg / ml, and the re...
Embodiment 3
[0065] This embodiment provides a method for constructing a silk fibroin / silver phosphate nanowire composite pore scaffold, which includes the following steps:
[0066] Prepare a silk fibroin-silver nitrate mixed solution, where the silk fibroin concentration is 4%, the silver nitrate concentration is 2%, and the mass ratio of silk fibroin to silver nitrate is 2:1;
[0067] Pour the mixed solution into a mold placed horizontally on a metal plate at -80°C. After fully freezing, transfer the resulting ice cubes to a freeze dryer for drying. After the ice crystals sublimate, the white porous solid obtained is silk fibroin. Protein-oriented channel scaffold;
[0068] The above-mentioned oriented porous scaffold is placed in a phosphoric acid solution with a surfactant PAA concentration of 0.15 mg / ml, wherein the phosphoric acid solution uses ethanol as the solvent, and the mass volume ratio of the phosphoric acid solution is 2.6 mg / ml. The reaction product is obtained by reacting for 4 h...
