项目摘要

The proposed work will solve a fundamental manufacturing issue: the inability to directly pattern metal with sub-100nm resolution. Addressing the nanopatterning of silver, which finds application in photonics and electronics, it develops a novel solid-liquid electrochemical process capable of large-area, low-cost and high fidelity patterning. In addition to deriving a fundamental physical understanding of transport of metallic ion species across multi-phase domains such as ionic glass-liquid electrolyte systems, the proposed research will exploit high speed, continuous, direct nanoscale patterning of metallic substrates to generate high performance biosensors.If successful, the proposed research will provide the manufacturing community with a valuable new technology. The obtained knowledge of the physical, chemical, and transport properties of silver-based solid electrolyte material systems can be used in the design and industrial-scale manufacturing of optical biosensors. In addition, the understanding developed in this research can be translated to other similar systems, such as liquid junction photovoltaic devices and lithium ion batteries with nanostructured anodes thus inspiring similar systems to be studied and developed for a range of applications including renewable energy conversion and new sensor designs.

拟议的工作将解决一个基本的制造问题：无法以低于 100 纳米的分辨率直接对金属进行图案化。针对银纳米图案在光子学和电子学中的应用，该公司开发了一种新型固液电化学工艺，能够实现大面积、低成本和高保真度图案化。除了获得对金属离子在离子玻璃-液体电解质系统等多相域中的传输的基本物理理解之外，拟议的研究还将利用金属基底的高速、连续、直接纳米级图案化来生成高性能生物传感器。如果成功，拟议的研究将为制造界提供一项有价值的新技术。所获得的银基固体电解质材料系统的物理、化学和传输特性的知识可用于光学生物传感器的设计和工业规模制造。此外，这项研究中形成的理解可以转化为其他类似的系统，例如液体结光伏器件和具有纳米结构阳极的锂离子电池，从而激发类似系统的研究和开发，以应用于可再生能源转换和新传感器设计等一系列应用。
