Biomineralization Mimetics and Particle Synthesis in Microstructured Environments

本课题研究的是两类材料的合成。首先是生物矿物质，特别是碳酸钙，这是生物矿化研究中定义明确的模型。这里的目标是开发用于控制晶体大小和形态的系统。所选择的仿生环境是那些对成矿起空间和构造控制作用的环境。将使用反胶束和朗缪尔-布洛杰特(LB)膜。此外，还将研究通过几何和立体化学晶格匹配来调节矿化的蛋白质的作用。第二类材料是锌、镉硫化物和硒化物的半导体纳米团簇。合成将再次通过使用反胶束环境进行。现场控制将通过使用笼状水合物形成的新方法来执行，该项目将研究水合物的形成对颗粒大小和结构的影响。

This project is to research the synthesis of two classes of materials. The first is biominerals, in particular, calcium carbonate, a well defined model in biomineralization studies. The objective here is develop systems for the control of crystal size and morphology. The biomimetic environments selected are those that exert spatial and structural control of mineralization. Reversed micelles and Langmuir-Blodgett (LB) films will be used. In addition, the role of proteins that regulate mineralization through geometric and stereochemical lattice matching will be investigated. The second class of materials is semiconductor nanoclusters of zinc and cadmium sulfides and selenides. Synthesis will again be approached through the use of reverse micelle environments. Control in-situ is to be carried out by a novel approach using clathrate hydrate formation, and this project will examine the effects of hydrate formation on particle size and structure.
