本文采用x射线衍射、红外光谱和扫描电子显微镜等方法研究了胆固醇/卵磷脂/壳聚糖体系中碳酸钙模拟生物矿化过程。通过改变有机基质的组成,使有机基质的模板作用也发生改变,从而使生成方解石型碳酸钙的模板可生成球霰石型的碳酸钙。文中还进一步探讨了体系中壳聚糖、卵磷脂、胆固醇三者的协同作用对生成碳酸钙晶型的影响。
本文採用x射線衍射、紅外光譜和掃描電子顯微鏡等方法研究瞭膽固醇/卵燐脂/殼聚糖體繫中碳痠鈣模擬生物礦化過程。通過改變有機基質的組成,使有機基質的模闆作用也髮生改變,從而使生成方解石型碳痠鈣的模闆可生成毬霰石型的碳痠鈣。文中還進一步探討瞭體繫中殼聚糖、卵燐脂、膽固醇三者的協同作用對生成碳痠鈣晶型的影響。

The process of calcium mimetic biomineralization in the chitosan-phospholipid-cholesterol system is reported in this paper, and is charasterized by using XRD, SEM and IR. The model action is changed through changing the composition of organic base. Vaterite can be created in organic base in which calcite was created before. Keeping the ratio of phospholipid and cholesterol constant, the largest quantity of vaterite can be gained as chitosan concentration is 4g·L-1. When chitosan concentration is constant, with the ratio of phospholipid and cholesterol increasing, more vaterite can be gained. The template of biomimeralization can be assumed due to that the action of chitosan could e modified by phospholipid and cholesterol, and the surface of forming crystal is changed to higher energy surface. So the vaterite with high energy can be gained easily. At last we think that the largest quantity of vaterite can be gained when chitosan, phospholipid and cholesterol are in existence with a proper ratio.
