The invention discloses a bacterial cellulose/biological ceramic composite membrane loaded with growth factors and a preparation method thereof. The composite membrane is based on bacterial cellulose membrane, and is loaded with growth factors on its surface in the form of gel deposition coating, and then It is obtained by coating the bioceramic membrane on its surface by electrospinning technology; both the bacterial cellulose membrane and the bioceramic membrane have a nanofiber structure, which is used as a tissue repair material and has sufficient contact space with the cell environment of the damaged tissue; at the same time, It has a good effect of maintaining the activity of growth factors, and can control the release rate of growth factors by controlling the degradation rate of the composite membrane, and has good application value in tissue repair such as promoting tissue division and cell regeneration. |
