Abstract: Optical tweezers offer a non-contact approach to control the position and orientation of mesoscale objects using optical forces, and can even assemblemicro-/nanostructures from different materials. Among them, optical manipulation of metallicnanomaterials is especially complex due to their unique plasmonic properties. In this talk, I will discuss the interactions of light with plasmonicnanostructures and introduce the technique of using structured optical fields to tailor optical trapping and manipulation of silver and gold nanostructures. I will also show light-mediated self-organization of silver nanoparticles via optical binding interactions, and discuss how electrodynamics potential energy surfaces and the associated reaction paths govern self-organization of optical matter.
