Correlated Structure-Function Study of Single Metallic Nanoparticles

The focus of nanoplasmonic research in the Van Duyne group is to thoroughly study the structure (shape, size) – function (Localized Surface Plasmon Resonance (LSPR)) relationship for noble metal nanoparticles. Our goal is to understand and predict plasmonic properties in order to engineer particles displaying large surface-enhanced Raman spectroscopy (SERS) enhancement and high refractive index sensitivity (RIS). We have developed high throughput correlative LSPR/TEM/(SERS or RIS) methods based on pattern matching of Rayleigh scattering and transmission electron microscopy (TEM) images to identify, characterize, and image single ‘nanoantennas’. Computational work (FDTD and FEM calculations) is performed in collaboration with the Schatz group.
