We measure the femto-Newton forces produced by 2D surface plasmon optical traps able to trap micro-colloids at a patterned metal surface under low laser intensity.
Avalanche concentration, a rapid long-range accumulation of particles around a laser spot in a liquid sample, is demonstrated and characterized for VO2 nanorods. The effect is found to be driven by a convective flow in the sample, caused by efficient heating of VO2 nanorods that transition from insulator to metal within the laser spot.
We present plasmonic tweezers that makes use of localized surface plasmons from a close-packed Au nanoparticle (NP) array. This device is able to realize long-range trapping and orientation control of single nanorods with a very low optical intensity requirement.
