This Materials World Network project aims to develop various novel strategies to achieve control over self-assembled DNA nanotubes. A bio-mimetic self-assembly approach is taken to use DNA as programmable construction building block to engineer and develop novel nanostructured materials. The goals of this international collaboration are aimed at: 1) Mimicking nature's strong microtubule structure to design spiral DNA nanotubes that will have improved mechanical properties; 2) Developing surface alignment methods to assemble DNA nanotubes into two-dimensional networks, thereby bridging the bottom-up self-assembly with top-down lithographic approaches together; 3) Achieving improved DNA templated nanowire formation based on stronger mechanic properties of the DNA nanotubes and their alignment on surface. This project involves extensive collaboration between Arizona State University (Dr. Yan) in US and Dresden University of Technology (Dr. Mertig) in Germany.The intellectual merit of the project lies in that DNA nanotube templated nanowire or nanoparticle assembly provides unprecedented opportunities to explore electronics/magnetics/optical properties with novel annular geometries in nanoscale domains. The bio-inspired self-assembly may prove useful in creating computer chips with smaller feature sizes. The project has broader impact by: 1) Integrating the research results into the material research curriculum developments at both universities. Examples of such courses include "Molecular Bioengineering" at Dresden and "Nanobiotechnology" at ASU; 2) Teaching "Bio-mimetic Self-assembly" topics to high school students through a high school outreach program; 3) Disseminating cutting-edge material research knowledge to a wider audience of minority communities and encourage underrepresented students to pursue careers in science.This award is co-funded with the Office of International Science and Engineering.

该材料世界网络项目旨在开发各种新颖的策略来实现对自组装 DNA 纳米管的控制。采用仿生自组装方法，使用 DNA 作为可编程构建模块来设计和开发新型纳米结构材料。此次国际合作的目标是：1）模仿自然界强大的微管结构，设计出具有改进机械性能的螺旋DNA纳米管； 2）开发表面对准方法将DNA纳米管组装成二维网络，从而将自下而上的自组装与自上而下的光刻方法结合在一起； 3) 基于 DNA 纳米管更强的机械性能及其表面排列，实现改进的 DNA 模板纳米线形成。该项目涉及美国亚利桑那州立大学（Yan 博士）和德国德累斯顿工业大学（Mertig 博士）之间的广泛合作。该项目的智力优势在于 DNA 纳米管模板纳米线或纳米粒子组装提供了前所未有的探索机会纳米级域中具有新颖环形几何形状的电子/磁学/光学特性。仿生自组装可能有助于制造具有更小特征尺寸的计算机芯片。 该项目通过以下方式产生更广泛的影响：1）将研究成果整合到两所大学的材料研究课程开发中。此类课程的例子包括德累斯顿的“分子生物工程”和亚利桑那州立大学的“纳米生物技术”； 2) 通过高中推广计划向高中生教授“仿生自组装”主题； 3) 向更广泛的少数群体群体传播前沿材料研究知识，并鼓励代表性不足的学生从事科学事业。该奖项由国际科学与工程办公室共同资助。
