Representative SEM images showing the interconnecting pores, distribution of deposited particles, and shape of (a) Gel and (b–d) HA/Gel scaffolds (original magnification: ×500, ×5000, and ×10,000.). (e, f) FTIR analyses of Gel and HA/Gel scaffolds that demonstrate the cross-linking reaction of gelatin and HA. (g) XRD standard card of HA. (h) XRD analysis of HA/Gel showing HA particles deposited on the Gel scaffolds.
