Abstract
We report the work in progress to develop a non invasive and fast optical method allowing characterizing the concentration, aspect ratio and mean size of acicular, nanorod and nanotube shaped particles. This method is based on the analysis of the spectral extinction of nanoparticles illuminated by polarized-light and whose orientation can be controlled by means of electrostatic and/or hydronamical forces. T-Matrix calculations and preliminary experimental results illustrate some aspects and features of this method.
