The free nano-HA, nanoclay, and their scaffolds were characterized via TEM, SEM, EDX, FTIR, XRD, and TGA analyses. <i>In vitro</i> bioactivity, degradation, swelling, and cytotoxicity were investigated. For the <i>in vivo</i> studies, two groups of rats were used (<i>n</i> = five) in the study period (37 days). The scaffolds were implanted in the rat’s back. TEM analysis showed the nanorods of HA have a particle length of around 107 nm and a width around 17 nm, which is crystalline in nature, as XRD demonstrated. However, the SEM images showed the formation of honeycomb-like scaffolds. The <i>in vitro</i> bioactivity results through the changes of PBS ions and SEM/EDX analysis after immersion in PBS detected the formation of a calcium phosphate layer which is important for bone regeneration.
