23 Jul Preparation method for spirulina polymer composite tissue engineering scaffold
Abstract
The invention discloses a preparation method for a spirulina polymer composite tissue engineering scaffold. The preparation method comprises the following steps: dissolving spirulina crude extract and polymer into an organic solvent in a mass ratio being 1: (2-20) to prepare a mixed solution with mass concentration being 10-25%, stirring for 24-48 hours, and uniformly mixing with a pore-foaming agent 7-10 times the mass of solid of the mixed solution; then, pouring the mixture into a mould with a needed shape to be subjected to room-temperature air-drying for 24-72 hours, drying for 24-48 hours at a temperature of 50-70 DEG C under vacuum degree of 0.001-0.01Mpa, taking out a sample in the mould and soaking the sample into deionized water, replacing the deionized water every 4-8 hours, getting out the sample after replacing for 18-40 times in total; and drying the sample for 24-48 hours at a temperature of 40-70 DEG C under vacuum degree of 0.001-0.01MPa. The spirulina polymer composite tissue engineering scaffold obtained by the method has the characteristics of being good in hydrophily, high in compression strength, quick to degrade and non-toxic.
