The present research proposal seeks to focus on an area of nanotechnology termed plasmonics. The field of plasmonics relies on the unique optical and electronic effects observed when certain nanoscale metals, such as the coinage metals, interact with incident electric fields, such as the electric field component of light. Such interaction generates what are termed surface plasmons, which can be either confined to the surface or can propagate along the surface of a nanometal, depending on its size and dimensions. These surface plasmons have remarkable attributes, most notably the ability to harvest and manipulate light at the nanoscale, leading to highly sensitive chemical sensing and unprecedented future developments in near-field optical microscopy and plasmonic circuitry. Such advanced materials have an enormous range of possible and demonstrated applications, ranging from enhanced solar-energy conversion to superlenses and optical cloaking. The research program outlined herein revolves around three main themes related to advanced molecular sensing using innovative plasmonic platforms: (i) enhanced sensitivity (ii) improved selectivity and (iii) future sustainability; these areas are summarized below.

目前的研究计划试图集中在一个被称为等离子体的纳米技术领域。等离子体场依赖于当某些纳米级金属（如铸币金属）与入射电场（如光的电场成分）相互作用时观察到的独特的光学和电子效应。这种相互作用产生了所谓的表面等离子体，它可以局限于纳米金属的表面，也可以沿着纳米金属的表面传播，这取决于它的大小和尺寸。这些表面等离子体具有显著的特性，最显著的是在纳米尺度上收集和操纵光的能力，导致高灵敏度的化学传感和近场光学显微镜和等离子体电路的前所未有的未来发展。这种先进的材料有着广泛的应用前景，从增强太阳能转换到超级透镜和光学隐形。本文概述的研究计划围绕与使用创新等离子体平台的先进分子传感相关的三个主要主题：(i)提高灵敏度（ii）提高选择性和（iii）未来的可持续性；这些方面总结如下。
