3D Printed Graphene Oxide/Calcium Alginate/Strontium-Doped Hydroxyapatite Composite Scaffolds with Enhanced Osteogenic and Angiogenic Properties for Critical-Size Bone Defect Repair.
The repair of critical-sized bone defects is hindered by insufficient vascularization, an unfavorable osteogenic microenvironment, and the limitations of conventional materials. Systematic studies on ternary composites of graphene oxide (GO), calcium alginate (CA), and strontium-doped hydroxyapatite (Sr-HA) remain limi...
