Light-driven self-assembly of two gold nanorods

Light-driven self-assembly of two coupled gold nanorods (GNRs) was studied theoretically. We analyzed the optical forces and torques on both GNRs. Our results show that due to the plasmon-mediated light-matter interaction two adjacent GNRs could coalesce in the end-to-end or side-by-side manner, depending on the wavelength and their initial configurations.
