Design of nano hydroxyapatite (nHA) releasable micro-whiskered bioceramics. (A) Schematic illustration of the fabrication process of micro-whiskered hydroxyapatite (wHA) bioceramics and the representative SEM images. (B) Schematic illustration of the preparation method of nHA loaded micro-whiskered hydroxyapatite (nwHA) bioceramics and the representative SEM images. (C) Ca²⁺ released profile of the nwHA bioceramics in Tris buffer (pH 7.4) in the first three days. The colored bars indicated the selected four nwHA bioceramics according to the difference in Ca²⁺ concentration. All data are reported as mean ± standard error.
