23 Jul Porous biological material using modified gelatin as crosslinking agent and preparation method of porous biological material
Abstract
The invention provides a porous biological material using modified gelatin as a crosslinking agent and a preparation method of the porous biological material. The preparation method specially comprises the following steps: dissolving an acrylamide monomer, methacrylamide modified gelatin and inorganic nano-clay in deionized water, and stirring for 10 to 30 minutes in an inert atmosphere; adding a catalyst, stirring for 5 to 10 minutes in the inert atmosphere, and then adding an initiator; performing radical polymerization for 12 to 48 hours at the temperature of -30 DEG C to 30 DEG C; soaking the reaction product in the deionized water at 20 DEG C for 48 to 72 hours, and replacing the deionized water every 5 to 8 hours, and finally performing freeze-drying on the reaction product for 24 to 48 hours to obtain the porous biological material using modified gelatin as the crosslinking agent. The preparation method is simple in preparation process, the condition can be controlled, and the prepared porous biological material has the characteristics of good biocompatibility, mechanical property, macroporous property, quick swelling property and the like at the same time, and can be widely applied in the fields of biological scaffolds, cell culture, drug controlled release, tissue engineering, trauma and burn treatment and other biomedical materials.
