The novel fastSPS setup is used to study the growth process of rodshaped gold nanoparticles in the presence of surfactant molecules. It is observed that the particles grow mainly in the direction of the short rod axis, resulting in a decrease of the aspect ratio. This is, to the best of my knowledge, the first real-time optical observation of nanoparticle growth on a single-particle level (results were published in reference ). In collaboration with Olaf Schubert the nanoparticle growth was also monitored using the novel RotPOL setup. Here a decrease of the average polarization anisotropy \(PA\) is observed.
