The US Department of Defense is awarding a team of nine professors from six universities $6 million over five years to exploit a precise biological assembly for the study of quantum physics in nanoparticle arrays. This research will help to produce a fundamental understanding of quantum electronic systems, which could impact the way future electronics are created.
美国国防部给予一个由6所大学的9名专家教授组成的团队 600万美元的预算，他们将用至少5年的时间开发一个精确的生物 学组件在纳米颗粒阵列中研究量子物理。这项研究将帮助我们对 量子电子系统有一个基本的认识，它将为未来的电子学的产生起 到重大作用。
The UCLA Henry Samueli School of Engineering and Applied Science (HSSEAS) is teaming up with leading researchers at the University of Minnesota, New York University, the University of Texas at Austin, the University of Pennsylvania and Columbia University to develop biological strat-egies combining DNA, proteins, and peptides with chemical synthesis techniques to construct arrays of nanoparticles.
加州大学亨利_萨缪理工程和应用科学学院将同明尼苏达大 学、纽约大学、德州大学奥斯丁分校、宾夕法尼亚大学和哥伦比亚 大学的主要研究者协作开发能够通过化学合成技术将DNA、蛋白 质和肽等组合成纳米颗粒阵列的生物技术。
Joining biological to man-made materials is the first step to a whole new materials assembly technique that will operate on the nanoscale. Interactions between precisely arranged metallic nanoparticles could lead to new physics discoveries— as well as to new mechanisms for computing, signal processing, and sensing.
将生物材料同人造材料相结合将是完全在纳米尺度下操作的 新材料装配工艺的第一步。在准确排列的金属纳米颗粒彼此所产 生的作用下可能会导致新的物理发现——同时也会在计算、信号 处理和传感方面产生新机制。
Basic studies of such nanoparticle arrays have in the past been hampered by the need to fabricate test structures with extreme control and precision. Most semiconducting devices, such as computer chips, are made from the top down. The biological assembly technique aims at building from the bottom up, atom by atom or molecule by molecule.
过去由于对这种纳米颗粒阵列基础研究必须有高度可控和精 确的实验设施而变得阻碍重重。多数半导体设备，例如计算机芯 片，是用自上而下的方法制造。生物装配技术的目标是由原子或分 子的由下而上的方法组装。
“By exploiting biology to precisely control size, spacing, composition, and coupling in the arrays, we will be able to examine the effects of electronic, magnetic, and optical interactions at much smaller dimensions than in the past. This will open a wide range of unbroken ground for exploring new physics，" said electrical and computer engineering professor Richard A. Kiehl of the University of Minnesota, who is leading the effort. Kiehl has a wide-ranging experience in investigating the potential of novel fabrication techniques, physical structures, and architectures for electronics.
作为项目负责人之一,明尼苏达大学的电子和计算机工程学教 授理査德.克尔这样说利用生物技术来精确控制颗粒阵列的尺 寸、间隔.成份和关联，我们将能在比过去小得多的范围观测电子、磁场和光的相互作用。这将为我们探索未知的物理学领域开辟一条崭新的道路。”克尔作过大量有 关新型制造技术潜能、物理结构和电子结构的调查。
The team members from the six universities include two professors from the UCLA HSSEAS, Yu Huang (materials science) and Kang L. Wang (electrical engineering), as well as UCLA professor Yeates (biochemistry); New York University professors Kent (physics) and Seeman (chemistry); University of Minnesota professor Kiehl (electrical and computer engineering); University of Texas at Austin professor MacDonald (physics); University of Pennsylvania professor Murray (chemistry); and Columbia University professor Nuckolls (chemistry).
这个团队来自6所大学，包括加州大学亨利?萨缪理工程和应用科学学院的两位教授,黄玉 (材料科学I)和王康（电子工程），以及加州大学学者叶茨(生物化学），纽约大学教授肯特(物理学） 和西曼(化学明尼苏达大学教授克尔（电子和计算机工程），德州奥斯丁大学教授麦克唐纳德(物 理），宾西法尼亚大学教授穆雷(化学）,哥伦比亚大学教授纳克尔斯(化学)。
Kiehl and Seeman have previously collaborated in the first demonstration of metallic nanoparticle assembly by DNA scaffolding, which will be central to this project. Seeman will exploit DNA nanotechnology to construct 2D and 3D scaffolding for the nanoparticle arrays, while Huang and Yeates will use peptides and proteins to make nanoparticle clusters for assembly onto the scaffolding. Murray and Nuckolls will synthesize metallic and magnetic nanoparticles with organic shells that will self-assemble to the scaffolding and control the interparticle coupling. Kent, Kiehl, and Kang Wang will carry out experiments to characterize the electronic, magnetic, and optical properties of the arrays. Kiehl and Kang Wang also have been collaborating for the past four years at the Center on Functional Engineered Nano Architectonics (FENA), a multiuniversity center headquartered at the UCLA HSSEAS. MacDonald will provide theoretical guidance for the studies and analysis of the experimental results.
克尔和西曼之前在金属纳米微粒会议上合作过DNA骨架的第一次演示,那将是这个计划的核 心。西曼将利用DNA纳米技术为纳米颗粒阵列建造两维以及三维的骨架,之后黄玉和叶茨将在骨 架上制造肽和蛋白质的纳米颗粒聚合体。穆雷和纳克尔斯将把金属磁性纳米颗粒和能够自己组装 成支架并能控制颗粒间耦合作用的有机物外壳合成到一起,肯特、克尔和王康将对阵列的电子学、 磁学和光学属性的特征进行实验。过去4年中,克尔和王康在纳米结构体系功能性改造中心也合作 过,纳米结构体系功能性改造中心总部设在加州大学亨利?萨缪理工程和应用科学学院,并在多 家大学设有分部。麦克唐纳德将为研究和分析试验结果提供理论指导。
