这项拟议的工作将解决一个根本的制造问题：无法直接绘制分辨率低于100 nm的金属图案。为了解决纳米银在光子学和电子学中的应用，它开发了一种新的固-液电化学工艺，能够大面积、低成本和高保真地形成图形。除了对金属离子在离子玻璃-液体电解质系统等多相区的传输有一个基本的物理理解外，这项拟议的研究还将利用金属衬底的高速、连续、直接的纳米图形来产生高性能的生物传感器。如果成功，拟议的研究将为制造业提供一种有价值的新技术。所获得的银基固体电解质材料体系的物理、化学和输运性质的知识可用于光学生物传感器的设计和工业化制造。此外，这项研究中形成的理解可以转化为其他类似的系统，如液结光伏器件和具有纳米结构阳极的锂离子电池，从而启发类似系统的研究和开发，用于一系列应用，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.
