Demonstrates scaffolds that promote bone formation in a rat model, suggesting an effective strategy for tissue repair.

The research aims to develop a novel scaffold that enhances bone regeneration by mimicking the structure of natural bone.
Constructed radially oriented hybrid scaffolds using directional freeze-casting technology.
Utilized tunicate nanocellulose as a dispersant and mechanical reinforcer with carbon nanotubes in a chitosan matrix.
Achieved biomimetic mineralization to produce uniformly distributed hydroxyapatite.
Evaluated the scaffolds' efficacy in a rat cranial defect model.
The oriented scaffold led to enhanced cell adhesion, alignment, and proliferation compared to random porous structures.
Demonstrated an antibacterial rate over 98% against S. aureus due to photothermal properties.
Bone mineral density reached 0.688 g/cm³ after 3 months of implantation, indicating strong osteogenic performance.
