Figure 1. Bioactivity evaluation of GPMgCl in α-MEM up to 168 h of immersion: (A-D) FTIR spectra of GPMg0Cl, GPMg5Cl, GPMg10Cl, and GPMg20Cl immersed in α-MEM for 0, 6, 24, 72, and 168 h, respectively; (E-H) Concentration of Ca, Mg, Si, and P ions in α-MEM after GPMg0Cl, GPMg5Cl, GPMg10Cl, and GPMg20Cl immersion for 6, 24, 72, and 168 h; (I) pH variation at 6, 24, 72, and 168 h. The ion concentrations and pH value of 0 h represent the initial ion concentrations and pH of α-MEM. α-MEM: Minimum essential medium-α; FTIR: Fourier-transform infrared spectroscopy; GPMgCl: Mg-doped chloride-containing bioactive glasses.
