Highly Tunable Surface Plasmon Enhanced Optical Transmission Through Periodic Nanostructures

该奖项由化学系化学测量和成像项目资助，爱荷华州立大学的Andrew C. Hillier教授和他的研究生研究人员将获得资助，开发利用周期性（衍射）纳米结构对分析物进行光谱检测的新方法。该研究将利用金属涂层周期纳米结构的等离子体特性来增强对分子吸附物的检测。希利尔小组还将致力于开发理论模型，以更好地理解这些纳米结构所带来的光谱增强。表面等离子体增强光谱学是一种比其他检测方法灵敏度更高的分析方法。希利尔教授和他的学生同事的工作旨在为科学家提供改进的化学物种探测器。这项研究很重要，因为它可能会导致检测低浓度化学物质的方法，这在包括半导体加工、化学试剂检测等多种技术领域都很重要。除了这项研究的更广泛的科学影响外，参与这个项目的学生将接触到分析化学的前沿研究。

In this award, funded by the Chemical Measurement and Imaging Program of the Division of Chemistry, Professor Andrew C. Hillier of Iowa State University and his graduate student researchers will be supported to develop new methods for spectroscopic detection of analytes using periodic (diffractive) nanostructures. The research will use metal-coated periodic nanostructures' plasmon properties to enhance the detection of molecular adsorbates. The Hillier group will also work on developing, theoretical models to better understand the spectroscopic enhancements seen with these nanostructures. Surface plasmon-enhanced spectroscopy is analytical method that provides improved sensitivity over other detection methods. The work of Professor Hillier and his student colleagues is aimed at providing scientists with improved detectors for chemical species. This research is important in that it may lead to methods that can detect chemical species at lower concentration, which could be important in diverse technological areas including semiconductor processing, chemical agent detection, etc. Besides the broader scientific impact of this research, the students participating in this project will be exposed to cutting-edge research in analytical chemistry..
