项目摘要

This grant promotes the progress of science by exploring the fundamental design principles behind the roll-imprint process for manufacturing nanomagnetic arrays for a wide range of applications, including individualized nanomedicine and radar thus advancing national health, prosperity and security. Current nanomedicine uses magnetic iron oxide nanoparticles in bio-labels for cancer diagnosis and therapy and for magnetic resonance imaging (MRI). Magnetic thin films are promising in circulators that block reflections from re-entering radar sources, hence eliminating noise and enhancing performance. This project disrupts both of these diverse technologies using three dimensional (3D) nanomagnetic arrays. The arrays are essentially groupings of barcoded nanowires that can be visualized as the pelt of a porcupine - shrunk to fit on the tip of a pen. Individually, the 'quills' are so small that they are internalized by cells, leading to effective cellular barcoding. As an array, or 'pelt', the quill or nanowire assembly acts like a one-way mirror for radar signals. The manufacturing process developed here enables rolls of 3D nanomagnetic arrays to be produced with a yield of one billion nanowires per minute. Undergraduate and graduate student training by two female electrical engineers supports education and diversity and enables students to conduct research in medical diagnosis and radar for self-driving cars for the benefit of society.Fundamental design principles are established for roll-imprint manufacturing of three dimensional (3D) nanomagnetic arrays, including nanostructure design, process design, and quality control design. Two underlying testbeds, radio-frequency identification (RFID) bio-labels and high frequency circulators for self-driving cars, are used to verify the designs. For nanostructure design, hierarchical nanostructures are composed of zero dimensional (0D) nanodisks stacked into one-dimensional (1D) nanowires that are inside two-dimensional (2D) arrays of columnar nanopores to make three-dimensional (3D) structures. The magnetic spin structures are simulated to facilitate design with experimental verification. The process design involves roll-imprinting of aluminum before anodization to produce aluminum oxide templates containing columnar nanopores with long range order. Electrodeposition is then used to fill these nanopores with single component ferromagnetic metals and multilayers according to the desired nanostructure designs. Quality control design involves high frequency circuits, including coplanar waveguides to measure ferromagnetic resonance and custom designed circulators to measure composite properties. Importantly, the quality control design is directly applicable for testbed success. Previous work has successfully demonstrated 3D nanomagnetic arrays that were synthesized using planar components with areas of square-centimeter. This work scales up manufacturing to square-meter per hour rates in a step-continuous roll-to-roll process.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项赠款通过探索用于制造纳米磁性阵列的滚动图形流程背后的基本设计原则，以促进科学的进步，其中包括个性化的纳米医学和雷达，从而促进了国家健康，繁荣和安全。当前的纳米医学在生物标签中使用磁氧化铁纳米颗粒进行癌症诊断和治疗以及磁共振成像（MRI）。磁性薄膜在循环器中有希望，这些循环器会阻止重新输入雷达源的反射，从而消除噪声和增强性能。该项目使用三维（3D）纳米磁阵列破坏了这两种不同的技术。阵列本质上是一组条形码的纳米线，可以将其可视化为豪猪的毛皮 - 缩水以适合笔尖。单独的“羽毛笔”是如此之小，以至于它们被细胞内化，从而导致有效的细胞条形码。作为阵列或“毛皮”，鹅毛笔或纳米线组装就像雷达信号的单向镜子一样。此处开发的制造过程使3D纳米磁阵列的卷能够以每分钟十亿纳米线的产量生产。两名女性电气工程师的本科和研究生培训支持教育和多样性，并使学生能够在社会上进行自动驾驶汽车的医学诊断和雷达研究。建立了额外的设计原理，用于三个二维（3D）纳米磁性阵列的滚动图形制造，包括Nananostrusture阵列，包括Nananostrusture阵列，包括Nananostrusture Design，包括Nananostrusture Design，流程设计，流程设计，质量设计。两个基础测试台，用于自动驾驶汽车的射频识别（RFID）生物标签和高频循环器用于验证设计。对于纳米结构设计，层次纳米结构由零尺寸（0D）纳米词组成，这些纳米词堆叠成一维（1D）纳米线，这些（1D）纳米线在二维（2D）圆柱纳米孔中，以制造三维（3D）结构。模拟磁性自旋结构以促进实验验证的设计。该工艺设计涉及在阳极氧化前的铝板涂片，以产生含有远距离顺序的柱状纳米孔的氧化铝模板。然后，电沉积用于根据所需的纳米结构设计，用单个组件铁磁金属和多层填充这些纳米孔。质量控制设计涉及高频电路，包括共面波导，以测量铁磁共振和定制设计的循环器以测量复合性能。重要的是，质量控制设计直接适用于测试床成功。先前的工作成功证明了使用平面成分的平面成分合成的3D纳米磁阵列。这项工作以逐步连续的卷到滚动过程将制造业范围扩大到平方米的每小时。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来获得支持的。
