23 Jul Hydrogel with adjustable structure size, preparation method and application thereof
Abstract
The invention discloses a hydrogel with adjustable structure size, a preparation method and an application thereof, belonging to the field of biomedical materials. The preparation method of the hydrogel comprises the following steps: firstly, gelatin microspheres with different sizes were prepared, then the gelatin microspheres were immersed in the solution containing growth factors or drugs to obtain drug-loaded gelatin microspheres, and then the drug-loaded gelatin microspheres were mixed with the desired hydrogel, and seeded with the desired seed cells to obtain the hydrogel with adjustablestructure size. The size of the hydrogel prepared by the method can be adjusted according to the practical application, and the specific function can be obtained by combining the required growth factors or drugs, and the gel matrix material is suitable for the growth of the specific seed cells, and finally the hydrogel with the specific tissue repair function is prepared, and the hydrogel has a broad application prospect in the tissue engineering repair.
