| titleOfInvention | Direct-writing forming 3D printing biological ink and preparation method thereof |
| abstract | The invention provides direct-writing formed 3D printing biological ink and a preparation method thereof, the direct-writing formed 3D printing biological ink is formed by mixing cellulose nanofiber-dopamine methacrylic acid 2-aminoethyl hydrogel and FBS-containing biological cell DMEM complete culture basis suspension, and the weight ratio of the cellulose nanofiber-dopamine methacrylic acid 2-aminoethyl hydrogel to the FBS-containing biological cell DMEM complete culture basis suspension is as follows by mass percent: 60-90% of cellulose nanofiber-dopamine methacrylic acid 2-aminoethyl ester hydrogel and 10-40% of FBS-containing biological cell DMEM complete culture basis suspension. The preparation method of the direct-writing forming 3D printing biological ink is simple and easy to implement, and the prepared direct-writing forming 3D printing biological ink has good biocompatibility, can promote cell adhesion and can be subjected to photocuring forming, so that the prepared 3D printing structure has good stability. |
