“…Single-beam optical traps have been used for almost two decades 13 to manipulate and interrogate objects of micrometre and nanometre size 14 . In 1994, optical confinement of metal particles in two dimensions was achieved 15 and it was shown 16 that a 36-nm-diameter gold particle could be optically trapped in three dimensions. More recently, birefringent crystals were rotated in an optical trap by angular momentum transfer 17 , and CuO nanorods were manipulated in two dimensions with a line optical trap 18 .…”

“…[1][2][3][4][5][6][7][8][9] This paper investigates the laser induced optical forces of metallic nanoparticle clusters when their localized surface plasmons ͑SPs͒ are excited. Such forces are important because they may affect the signal of surface enhanced Raman spectroscopy 10,11 or promote controllable aggregation of nanoparticles.…”

“…In the case of optical trapping of absorbing metallic microobjects, there is an upper limit on the particle size that can be trapped stably in 3-D using exclusively optical forces; this is due to a more complex scattering pattern and associated effects such as heating and electron motion in the skin depth of the metal. Thus, manipulation of larger absorbing objects is limited to confinement against the surface in a single-beam trap [20][21][22] or a scanning beam trap [23]. …”
