Prof. Reinhard was recently awarded a 3 Year renewal of her National Science Foundation Division of Chemistry (NSF-CHE) Grant titled: Plasmon Coupling Correlation Spectroscopy. This will help Prof. Reinhard and his research group investigate the unique optical properties and strong field localization properties of plasmonic nanoparticles as they are important components of many chemical sensing technologies and Efield enhanced spectroscopies. The research will advance the field of chemical imaging and sensing by introducing the concept of correlation spectroscopy to localized surface plasmon resonance (LSPR) spectroscopy. The ambitious research plan will utilize distance-dependent near-field coupling between plasmonic nanoparticles that cause spectral fluctuations in the far-field to monitor interparticle separations at signal intensities that are manifold higher than that of conventional dyes. Importantly, due to their superb photophysical stability plasmonic nanoparticles overcome existing limitations of fluorescence based correlation approaches in terms of maximum observation time and will facilitate a continuous signal correlation over a much longer time than is currently possible with fluorescence based approaches entirely without blinking. The research funded by this grant is transformative as it will facilitate the application of optical signal correlation techniques to systems that have, so far, not been accessible with conventional fluorescence-based correlation methods.

 

Besides the scientific impact, the research project has a series of educational and outreach components as well as detailed plans to encourage the participation of underrepresented groups in science and engineering. The grant will allow for the development of new course work and training opportunities for students from the high-school to graduate school level. Furthermore, Dr. Reinhard will organize annual workshops for students from inner city high schools, which typically have high representations from groups underrepresented in science and engineering. His main goal is to enthuse these students about the research of the proposal and to attract them to a career in STEM fields. The course material developed during the lifetime of the project will be disseminated via the PI’s homepage to further enhance the broader impact of this proposal.
