3D printed gellan gum/graphene oxide scaffold for tumor therapy and bone reconstruction

Compared with traditional tissue engineering scaffold processing methods, 3D printing technology has obvious advantages in achieving high structural complexity, flexibility and specific patient needs. Printing ink materials with both high printability and biocompatibility remains a major challenge. Herein, a hydrogel bio-ink with excellent thixotropy and recovery properties was prepared by combining gellan gum (GG) and graphene oxide (GO) for...
