Plasmonic optical trapping of soft nanomaterials such as polymer chains and DNA: micro-patterning formation
Localized surface plasmons exert a strong radiation force on nanoparticles in the vicinity of noble metal nanostructures, resulting in optical trapping. Such plasmon-based optical trapping is one of the hot topics in the field of nanophotonics and can be applied to molecular manipulation techniques. In this review paper, we describe the plasmon-based optical trapping of polymer chains and DNA. In addition, we describe the future outlook for this trapping method.
