The objective of this research is to develop a novel and versatilenano-manufacturing technology for fabricating defined numbers of nanowire rings on polymer microsphere surfaces. The approach combines compression-induced cracking of polymer-supported thin films, surface chemistry manipulation, and electroless deposition of metals. Detailed relationships between microsphere size, surface film property, degree of compression, electroless deposition procedure, and the type of nanofeatures generated will be determined to enable a cost-effective and well-controlled nanomanufacturing scheme.This proposal is motivated by the general need for novel nano-manufacturing technologies and concepts. The ability to manufacture micro- and nanospheres with defined sizes, compositions, surface charges, and surface patterns has been critical for advances in many fields such as in the generation of opals, preparation of photonic band gap materials, development of novel electronic devices, manipulation and analysis of biological cells, and production of inks, paints, cosmetics, and other rheological fluids. Most microspheres prepared to date, however, have relatively simple surface structures such as uniform coatings or the "capping" of one half of a sphere. The more elaborate nanopatterned microspheres that will be manufactured through this project will open new possibilities in advanced materials, electronics, and biology. Another important feature of the program is the integration of research and education through the training of students in a technologically significant area. This project is visually striking, experimentally straightforward, and theoretically stimulating. It will provide valuable hands-on laboratory experiences in nanomanufacturing research to graduate and undergraduate students and inspire the next generation of nanotechnology scientists and engineers.

本研究的目的是开发一种新颖的多用途纳米制造技术，用于在聚合物微球表面制造一定数量的纳米线环。该方法结合了压缩引起的聚合物支撑薄膜开裂、表面化学处理和化学沉积金属。微球尺寸、表面薄膜性质、压缩程度、化学沉积过程和生成的纳米特征类型之间的详细关系将被确定，以实现成本效益和良好控制的纳米制造方案。这一提议的动机是对新型纳米制造技术和概念的普遍需求。制造具有特定尺寸、成分、表面电荷和表面图案的微纳米球的能力对于许多领域的进步至关重要，例如蛋白石的生成、光子带隙材料的制备、新型电子器件的开发、生物细胞的操作和分析，以及油墨、油漆、化妆品和其他流变流体的生产。然而，迄今为止制备的大多数微球表面结构相对简单，如均匀涂层或球体一半的“封盖”。通过该项目将制造出更精细的纳米微球，这将为先进材料、电子和生物学开辟新的可能性。该计划的另一个重要特点是通过在技术重要领域培训学生，将研究和教育结合起来。这个项目在视觉上引人注目，实验上直截了当，理论上令人兴奋。它将为研究生和本科生提供宝贵的纳米制造研究实践实验室经验，并激励下一代纳米技术科学家和工程师。
