The proposed research aims to develop unique biomimetic scaffolds for the synthesis and assembly of novel multi-component metal oxide materials. Biomineraliztion processes result in an expansive array of complex materials. Inspired by silica condensing systems found in diatoms and sponges, the potential use of the awesome discriminating power of biology to drive nanoscale assembly will be explored. Specifically, (1) Develop a series of biomimetic templates capable of catalyzing the formation of Si02, Ti02, Ga203 and Ge02. (2) Capitalize on the biomimetic template's structure and function to prepare novel metal oxide composites incorporating additional nanoscale material or biological components. (3) Assemble novel composite metal oxide materials through patterned biomimetically active surfaces. By bridging two previously unconnected but crucial areas of nanoscience and biotechnology, steps towards bringing the power of biological materials synthesis of hierarchical multi-component systems will be made.

本研究旨在为新型多组分金属氧化物材料的合成和组装开发独特的仿生支架。生物矿化过程产生了一系列复杂的材料。受硅藻和海绵中发现的二氧化硅冷凝系统的启发，将探索利用生物学令人敬畏的辨别能力来驱动纳米级组装的潜在用途。具体而言，(1)开发一系列能够催化形成Si02、Ti02、Ga203和Ge02的仿生模板。(2)利用仿生模板的结构和功能，制备含有额外纳米级材料或生物成分的新型金属氧化物复合材料。(3)通过模式化仿生活性表面组装新型复合金属氧化物材料。通过将纳米科学和生物技术这两个以前没有联系但至关重要的领域连接起来，我们将朝着将分层多组分系统的生物材料合成的能力迈进一步。
