The characterization of bredigite scaffolds. (A) The schematic and scanning electron microscopy images of the BRT-R and BRT-O scaffolds. (B) The micro-FTIR spectra and mappings of the scaffolds. (C) The compressive strength of the scaffolds. (D) Weight loss (%) of the scaffolds after soaking in buffer for different time periods. (E) The pH value change after soaking the scaffolds at different time points. The (F) Ca, (G) Mg and (H) Si concentration in Tris buffer at different time points. The data were expressed as mean ± standard deviation (SD) (n = 3). ^***p < 0.001 vs. BRT-R. Scale bar: A, 1 mm and 5 μm
