Ultralong hydroxyapatite nanowires/collagen scaffolds with hierarchical porous structure, enhanced mechanical properties and excellent cellular attachment

Hydroxyapatite/collagen (HAP/Col) composite porous scaffolds have been extensively investigated in the field of bone tissue engineering due to their similar chemical composition to that of natural bone and good biocompatibility. However, the relatively poor mechanical properties of the HAP/Col composite porous scaffolds limit their application in bone regeneration. In order to overcome these limitations, the hierarchical porous ultralong...
