Abstract: | Precise manipulation and sorting of nanomaterials cannot rely on techniques used for micro- and macro-scale objects because of their nanoscale size, which is smaller than the diffraction limit, and their fast Brownian diffusion. To overcome the limitations of standard optical tweezers, new techniques have recently emerged that make use of optical forces acting on nanomaterials in the vicinity of photonic and plasmonic nanostructures. This review focuses on the techniques that have been recently developed to either optically transport, sort, trap, rotate, assemble, or deposit nanomaterials using photonic or plasmonic devices. The first part is dedicated to the optical transport and sorting of nanomaterials using photonic waveguides. The second part provides an overview of the recent work on optical trapping and manipulation of nanomaterials using photonic and plasmonic nanoresonators. The third part provides a short summary of recent work on optical trapping and manipulation using metalenses and metasurfaces. This review aims to highlight some specific functionalities enabled by photonic and plasmonic devices that make it possible to tailor the optical forces acting on nanomaterials. |
