Distance and orientation measurement in the nanometric scale based on polarization anisotropy of metallic dimers

We show that the orientation of a dimer and the distance between the nanoparticles that form it can be determined by measuring the scattering under polarized light illumination. Scattering microscopy has shown to be an alternative to fluorescence as it provides nonbleaching and highly biocompatible...
