This proposal was received in response to Nanoscale Science and Engineering initiative, NSF 02-148, category NIRT. The research involves the assembly of complex structures that contain ferroelectrics, metals, synthetic polypeptides, nanowires and nanotubes and the behavior that results from interfacing these structures at the molecular and nanoscale level. The research defines a new paradigm for fabricating multi component nanoscale structures that combines many advantages of self-assembly with the ability to selectively position dissimilar nanoscale elements. The approach exploits coupling to atomic polarization of ferroelectric domains and the specificity of nucleotide interactions. Engineered nanostructural elements are incorporated into complex configurations; including optically active porphyrin based compounds, designed polypeptides, nanotubes, nanowires, and particles. Several approaches are used to determine the properties of individual molecular and nanostructural elements and proximity effects in electrical and optical behavior. Enthusiastic research efforts in several fields have yielded a wide array of functional nano structures, including particles, wires, tubes, dots, organic molecules, and biological molecules. And device concepts abound. The potential of nanostructures can not be realized until multiple constituents can be co assembled and until the behavior of these constituents are understood. The award is jointly supported within Mathematical and Physical Sciences directorate through the Division of Materials Research (Ceramics and Solid-State Chemistry programs) and the Division of Chemistry. The Office of International Science and Engineering in the Directorate for Social, Behavioral and Economic Sciences is also contributing to this award.

本提案是对NSF 02-148 NIRT类纳米科学与工程倡议的响应。这项研究涉及包含铁电、金属、合成多肽、纳米线和纳米管的复杂结构的组装，以及在分子和纳米水平上将这些结构连接起来所产生的行为。这项研究为制造多组分纳米结构定义了一种新的范式，它结合了自组装的许多优点和选择性定位不同纳米级元素的能力。该方法利用了铁电区与原子极化的耦合和核苷酸相互作用的特异性。设计的纳米结构元素被结合到复杂的构型中；包括基于光学活性的卟啉化合物、设计的多肽、纳米管、纳米线和颗粒。几种方法被用来确定单个分子和纳米结构元素的性质以及电学和光学行为中的邻近效应。在多个领域的热情研究工作已经产生了广泛的功能纳米结构，包括粒子、线、管、点、有机分子和生物分子。设备概念比比皆是。纳米结构的潜力只有在多个组分能够共同组装并且了解这些组分的行为之后才能实现。该奖项由数学和物理科学局通过材料研究(陶瓷和固态化学计划)和化学司共同支持。社会、行为和经济科学局的国际科学和工程办公室也为这一奖项做出了贡献。
