Optical
trapping and manipulation of nanostructures' has been published in Nature Nanotechnology 8 807-819 (2013). '
From the abstract: Optical trapping and manipulation of micrometre-sized particles was
first reported in 1970. Since then, it has been successfully implemented
in two size ranges: the subnanometre scale, where light–matter
mechanical coupling enables cooling of atoms, ions and molecules, and
the micrometre scale, where the momentum transfer resulting from light
scattering allows manipulation of microscopic objects such as cells. But
it has been difficult to apply these techniques to the intermediate —
nanoscale — range that includes structures such as quantum dots,
nanowires, nanotubes, graphene and two-dimensional crystals, all of
crucial importance for nanomaterials-based applications. Recently,
however, several new approaches have been developed and demonstrated for
trapping plasmonic nanoparticles, semiconductor nanowires and carbon
nanostructures. Here we review the state-of-the-art in optical trapping
at the nanoscale, with an emphasis on some of the most promising
advances, such as controlled manipulation and assembly of individual and
multiple nanostructures, force measurement with femtonewton resolution,
and biosensors.
