Embodiment 1
[0037] A preparation method for a tissue engineering scaffold suitable for human organ construction, specifically comprising the following steps:
[0038] (1) Dissolve sericin powder in deionized water to prepare a sericin solution with a concentration of 5.0% (W / V);
[0039] Chitosan is dissolved in the dilute hydrochloric acid solution that concentration is 0.1mol / L, is made into the chitosan solution that concentration is 2% (W / V);
[0040] Dissolve sodium glycerophosphate in deionized water to prepare a sodium glycerophosphate solution with a concentration of 50% (W / V);
[0041] (2) Below 20°C, weigh 0.68ml of the sericin solution obtained in step (1) and 5ml of the chitosan solution, stir and mix evenly, then add 1ml of the sodium glycerophosphate solution obtained in step (1) dropwise, and stir 30min;
[0042] Put the mixed solution into the mold, control the temperature of the mold at 37°C, and make the mixed solution gel into shape; then place the molded material at -2...
