Structural and compositional characterizations of the nwHA bioceramics. (A) Schematic illustration of bamboo-groove inspired design of nwHA bioceramics. (B) Schematic illustration of nwHA bioceramics with gradient nHA layers (first line) and the representative SEM (second line), TEM (third line) and micro-CT (fourth line) images of bioceramics and their degradation product. (C) XRD patterns of wHA, nHA and nwHA bioceramics. (D) Pore structure parameters rendered by micro-CT analysis and in vitro degradation profile of different nwHA bioceramics. All data are reported as mean ± standard error. ANOVA with Tukey's post hoc test *p < 0.05, **p < 0.01, ***p < 0.001.
