Paper Abstract

An objective-type dark-field imaging spectroscope is used for imaging the orientation of single nonspherical nanoparticles. This simple and effective technique is able to simultaneously provide the spectral and spatial information of single nanoparticles. The orientation information of the nanoparticles is determined by investigating their polarization dependent longitudinal and transverse plasmon resonant wavelengths. The determination of the nanoparticles’ orientation could be used as a complementary tool to fluorescent labeling in biological applications.
