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.

该提案是为了响应Nanscale科学与工程倡议，NSF 02-148，类NIRT。 该研究涉及包含铁电，金属，合成多肽，纳米线和纳米管的复杂结构的组装，以及由于在分子和纳米级水平上连接这些结构而产生的行为。该研究定义了一种用于制造多组分纳米级结构的新范式，该结构将自组装的许多优势与选择性定位不同的纳米级元素的能力相结合。 该方法利用了铁电域的原子极化和核苷酸相互作用的特异性。 设计的纳米结构元素被纳入复杂的配置中；包括基于光学活跃的卟啉化合物，设计的多肽，纳米管，纳米线和颗粒。 使用了几种方法来确定单个分子和纳米结构元件的特性以及在电气和光学行为中的接近效应。 在多个领域的热情研究工作产生了各种功能性纳米结构，包括颗粒，电线，试管，点，有机分子和生物分子。 和设备概念比比皆是。 直到能够组装多个成分和在理解这些成分的行为之前，才无法实现纳米结构的潜力。该奖项通过材料研究部（陶瓷和固态化学计划）和化学划分在数学和物理科学局共同支持。 社会，行为和经济科学局的国际科学与工程办公室也为该奖项做出了贡献。
