Paper Abstract

We found that plasmonic optical trapping of soft nanomaterials were driven not only by an enhanced optical force but also by thermophoretic force. Since thermophoresis exerted on the nanomaterials strongly depends on their size and the surrounding medium, it is potentially applicable for a manipulation method of nanomaterials. In the present study, by taking advantage of the thermophoresis, we demonstrated thermophoresis-assisted optical trapping of pyrene-labeled hydrophilic polymer chains on plasmonic nanostructures.
