| titleOfInvention | Functionalized nano-cellulose hydrogel and preparation method thereof |
| abstract | The invention relates to a functionalized nanocellulose hydrogel and a preparation method thereof, wherein the hydrogel is internally provided with a uniform porous reticular structure with the aperture of 30-100 microns, TEMPO oxidized cellulose is dispersed in water to prepare nanocellulose dispersion liquid, the nanocellulose dispersion liquid is mixed with cells to prepare biological ink, the biological ink is printed in an ionic cross-linking agent by using a 3D biological printing technology to prepare the functional nanocellulose hydrogel, and the shape of the functional nanocellulose hydrogel can be designed according to needs. The invention takes renewable resource cellulose as a raw material to prepare the functionalized nano-cellulose hydrogel which has excellent mechanical property and good biocompatibility and is suitable for biological printing, and the functionalized nano-cellulose hydrogel is used as a nano-cellulose-based tissue engineering material, in particular to one of tissues such as bones, cartilages, skins, blood vessels, livers, hearts and the like, widens the application range of the cellulose, and provides a new way for the application research of the cellulose in the biomedical field. |
