Characterization of the stability and phase transformation of ACMP/SIM in SBF. TEM images of the simvastatin and magnesium incorporated calcium phosphate nanocomposites (ACMP/SIM) with a Ca/Mg ratio of 10:1 dispersed in simulated body fluid (SBF) for (a) 0.5 h, (b) 3 h, (c) 96 h (insert: SAED patterns); (d) STEM images of ACMP/SIM dispersed in SBF for 96 h; (e) The Ca, Mg, P, O and C distribution mappings of selected area in Fig. 3d; (f) The atomic percentage of Ca, Mg, P and O in ACMP/SIM after being dispersed in SBF for different time; (g) XRD patterns of ACMP/SIM after being dispersed in SBF for different time points; (h) Ca K-edge XANES spectra of HAP standards, Mg3(PO4)2 standards, and ACMP/SIM samples dispersed in SBF for different time
