The morphology of the mineral dependents on the solution characteristics. The main component of mineral was hydroxyapatite containing a little of CO32- group which the Ca/P ratio is 1.53, similar to the major mineral component of bone tissue. The porosities of the mineralized and unmineralized 3-D porous PLGA were (84.86±8.52)% and(79.70±7.70)% respectively. The biomechanical strength was 0.784±0.156 N/mm2 in unmineralized PLGA and 0.858±0.145N/mm2 in mineralized PLGA.

结果：PLGA经碱性溶液水解处理后表面亲水性明显增强，在0.5倍SBF中仅有少量矿物沉积，在SBF及1.5倍SBF中矿化后表面可以形成明显的矿化物；矿化物的形态与矿化液的浓度有关；矿化物主要成分为羟基磷灰石，含有碳酸根成分，钙磷比为1.53，类似于人骨无机质。
