拟议的工作将解决一个基本的制造问题：无法以低于100纳米的分辨率直接图案化金属。针对银的纳米图案化，发现在光子学和电子学中的应用，它开发了一种新的固-液电化学过程，能够大面积，低成本和高保真图案化。除了对金属离子在离子玻璃-液体电解质体系等多相域中的传输有基本的物理理解外，该研究还将利用金属基底的高速、连续、直接纳米级图案化来产生高性能的生物传感器。如果成功，该研究将为制造业提供有价值的新技术。所获得的基于银的固体电解质材料系统的物理、化学和传输性质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，在这项研究中开发的理解可以转化为其他类似的系统，如液体结光伏器件和具有纳米结构阳极的锂离子电池，从而激发类似的系统进行研究和开发的一系列应用，包括可再生能源转换和新的传感器设计。

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.
