Collaborative Research: Surface Plasmon Resonance in the Mid-infrared

在化学测量和成像项目的支持下，北卡罗莱纳州立大学的Stefan Franzen和Jon-Paul Maria以及特拉华大学的Karl Booksh正在研究调节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组合的中红外光学特性。具体来说，这个多学科团队正在研究中红外的表面等离子体振荡，以及如何通过调节导电氧化物的纳米结构来调节这些振荡。金属纳米颗粒的掺入对这些光学现象的可调性的影响也在研究中。这项工作寻求对光如何与固体表面相互作用的新理解。它将为探测大分子和生物分子在坚固的氧化物表面上的附着提供新的机会，从而实现表面表征和传感的新机制。它还为研究生（特别是那些来自代表性不足群体的研究生）提供了通过pi完善的国际交流项目与波兰和中国的研究人员合作的机会。

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.
