Notes:
The porous apatite-wollastonite bioactive glass-ceramic (AW-GG) was made fromnano-precursor powders derived from sol-gel process, and shaped by dipping method with polymerfoam. The physical-chemical properties, bioactivity and biocompatibility of the materials werestudied by means of TG, XRD, SEM, TEM and so on. The bioactivity was investigated in simulatedbody fluid (SBF) and the biocompatibility was evaluated by co-culturing with marrow stromal cells(MSCs). The result shows that: the particle size of the AW precursor powders is 40~100nm; porousAW GC has three-dimensional pored structure with 300~500um macropores and 2~5um micropores;the materials possess high bioactivity and biocompatibility. Porous AW GC may therefore have greatpotential application as bone tissue engineering scaffold
