Collaborative Research: Surface Plasmon Resonance in the Mid-infrared

在化学测量和成像计划的支持下，教授。北卡罗来纳州立大学的斯特凡·弗兰岑和乔恩·保罗·玛丽亚和特拉华大学的卡尔·布克什正在研究调控表面化学相互作用的结构/性质关系，以及导电氧化物、金属纳米颗粒及其混合化合物的中红外光学性质。具体地说，这个多学科团队正在研究中红外中的表面等离子激元振荡，以及如何通过调制导电氧化物的纳米结构来调节这些振荡。通过掺入金属纳米颗粒对这些光学现象的可调性的影响也在调查中。这项工作寻求对光如何与固体表面相互作用的新理解。它将为探索大分子和生物分子在坚固的氧化物表面的附着提供新的机会，使表面表征和传感的新机制成为可能。它还为研究生(特别是那些来自代表性不足群体的研究生)提供了与波兰和中国的研究人员合作的机会，通过PIS久负盛名的国际交流项目。

With support from the Chemical Measurement and Imaging Program, Profs. Stefan Franzen and Jon-Paul Maria of North Carolina State University and Karl Booksh of the University of Delaware are investigating the structure/property relationships that regulate surface chemical interactions, and the mid-infrared optical properties of electrically conducting oxides, metallic nanoparticles, and their hybrid combinations. Specifically, the multidisciplinary team is studying surface plasmon oscillations in the mid-infrared, and how those oscillations can be tuned by modulating the nanostructure of conducting oxides. Effects on tunability of these optical phenomena by incorporation of metallic nanoparticles are also under investigation. The work seeks new understanding of how light interacts with solid surfaces. It will provide new opportunities to probe the attachment of macromolecules and biomolecules on robust oxide surfaces, enabling novel mechanisms for surface characterization and sensing. It also provides opportunities for graduate students (particularly those from underrepresented groups) to collaborate with researchers in Poland and China through the PIs' well-established international exchange programs.
