This proposal research is accommodation of a dual-beam focused ion beam (FIB) system for "milling" nanostructures is part of that initiative. Our broad goal is to develop a research competence and workforce trained in combining fabricated nanostructures with designer molecules. Examples of proposed molecule-based nanostructures are nanoscale electrode gaps for molecular electronics, nanofluidic enclosures for single molecule optics, probes for single-molecule electrochemistry, molecule-based sensor devices, nanoscale dielectrophoretic traps and sorters for nucleic acids and proteins, and nanostructured intelligent molecular coatings. Other applications of the FIB include prototyping novel device architectures, including molecule-based sensors, preparing materials for electron microscopy analysis, FIB tomography and other physical probes, and manufacture and characterization ofnanostructured materials.Broader Impacts: The FIB will have a synergistic impact on major new programs at Arizona State University that integrate solid-state and molecular nanosciences. Through the IGERT it will serve to train a new breed of nanoscientist, spanning the chemistry-physics-engineering- biology spectrum. Training and outreach will utilize mechanisms put in place by INVSEE (Interactive Nano-Visualization for Science and Engineering Education (http://INVSEE.ASU.EDU). It will also be used in science teacher preparation programs (ACEPT and its successor AM-STEP). An on-line display at the Arizona Science Center will help to bring the concepts of nanoscience to the general public.

这项建议的研究是住宿的双束聚焦离子束（FIB）系统的“铣削”纳米结构是该倡议的一部分。我们的广泛目标是发展研究能力和劳动力培训相结合的纳米结构与设计分子。所提出的基于分子的纳米结构的例子是用于分子电子学的纳米级电极间隙、用于单分子光学的纳米流体外壳、用于单分子电化学的探针、基于分子的传感器装置、用于核酸和蛋白质的纳米级介电电泳陷阱和分选器以及纳米结构智能分子涂层。FIB的其他应用包括原型设计新的设备架构，包括基于分子的传感器，准备材料的电子显微镜分析，FIB断层扫描和其他物理探针，和制造和表征ofnanostructured材料。更广泛的影响：FIB将有一个协同作用的影响，在亚利桑那州州立大学的主要新计划，整合固态和分子纳米科学。通过IGERT，它将有助于培养新一代的纳米科学家，跨越化学-物理-工程-生物学光谱。培训和推广将利用INVSEE（科学和工程教育互动纳米可视化）（http：//INVSEE.ASU.EDU）建立的机制。它还将用于科学教师准备计划（ACEPT及其继任者AM-STEP）。在亚利桑那科学中心的在线展示将有助于将纳米科学的概念带给公众。
