FTIR and NMR evidence of aluminosilicate microspheres bioactivity tested in simulated body fluid
چکیده انگلیسی


• Aluminosilicate microspheres prepared by spray drying;
• Structural effect of partial replacement of aluminum with yttrium;
• FTIR and MAS-MNR investigations;
• The test in simulated body fluid denotes bioactivity enhancement by yttrium addition.

70SiO2·30Al2O3 and 70SiO2·20Al2O3·10Y2O3 aluminosilicate microparticles with potential biomedical applications were investigated with respect to composition effect on structure and bioactivity tested in vitro, as response to simulated body fluid. The local structure of the samples was evaluated by Fourier transform infrared (FT-IR) and magic angle spinning nuclear magnetic resonance (MAS-NMR) spectroscopy. The results indicate that the addition of yttrium to aluminosilicate microspheres influences the surface properties and induces an enhanced bioactivity.
