(a) Compressive strength of FA- and ALN-impregnated nMBG@CPC after soaking in SBF for 24 h (n = 10); * between-group symbols are statistically significant (p < 0.05); (b) fracture microstructure and Si elemental mapping of FA- and ALN-impregnated nMBG@CPC after immersion in SBF for 24 h (Marked in the red circle is the relatively strong Si element mapping).
