牛血清白蛋白LB膜诱导方解石的生长

Calcite Crystals Growth was Induced by BSA LB film

采用模拟生物矿化的方法,研究了牛血清白蛋白(BSA)LB膜对碳酸钙晶体成核和生长的诱导控制作用。XRD、SEM结果表明:在BSA单层LB膜诱导下,形成形状规则、边缘清晰的多层盘状方解石晶体,且沿(104)晶面取向生长。说明牛血清白蛋白(BSA)LB膜对碳酸钙的形貌、生长取向性有很好的调控作用。

The influence and control of the bovine serum albumin （BSA） LB film on the nucleation and growth orientation of calcium carbonate were studied in the process of the biomineralization. The results of XRD show that the crystal grows only along the （104） and （208） faces, indicating a well orientation of calcite; SEM result shows that calcite crystal manifests the clear edge and multilayer disk-like crystal morphology. All the results suggest that BSA LB film can be used as a template to induce and regulate the calcium carbonate to crystallize with a special growth orientation and complex morphologies.
