title: Characteristic image patterns of single anisotropic plasmonic nanoparticles embedded in a gel matrix.
abstract: We present characteristic doughnut-shaped image patterns of gold nanorods embedded in a thin layer of a gel matrix observed under a dark-field microscope. The characteristic scattering field distributions allow us to estimate the spatial orientation of single gold nanorods. The measured scattering patterns are further verified by a simulation study.
