Characterization of the two-dimensional length and diameter distributions of gold nanorods by size exclusion chromatography.

ABSTRACT: Access to complex multidimensional property distributions of nanoparticle systems is indispensable for the understanding of their synthesis, processing and application in modern production technologies. Plasmonic gold nanorods are a system of particular interest due to their shape-dependent localized surface plasmon resonance. In this study, we show how the optical back coupling technique, previously developed for the analysis of sedimentation coefficient-resolved extinction spectra derived from analytical ultracentrifugation experiments, can be transferred to standard laboratory equipment, namely size exclusion chromatography. The optical back coupling method utilizes the unique spectral extinction of plasmonic nanoparticles such as gold nanorods and other geometries combined with their h
