3 Injectable three-dimensional nano fiber scaffolds and method for preparing the same

摘要

The present invention relates to an injectable three-dimensional nanofiber scaffold and a method for manufacturing the same. Injectable 3D nanofiber scaffolds according to the present invention, by coating a hydrogel on 3D electrospun biodegradable polymer nanofibers, grow cells in 3D, and at the same time, desire it in vivo through simple injection It was made possible to deliver to the site. In addition, in the process of delivering cells or drugs using the scaffold, it was confirmed that the cell proliferation activity could be maintained high while minimizing the detachment of cells by injection, and the drug release rate could be effectively controlled according to the hydrogel component. Bar, the present invention may be used as a core technology in the field of cell or drug treatment.
