In this study, focusing on nanostructures formed by Laguerre-Gaussian beam irradiation, we investigated the assembly dynamics of nanoparticles (NPs) as a model to understand the formation process of chiral nanostructures.
Analyzing the fluorescence intensity and areas at the laser focal spot, we evaluated the assembled structure of NPs. Furthermore, particle tracking analysis for NPs attracted to the focal spot from the outside was performed.
