Gold nanorods (NRs), pseudo-one-dimensional rod-shaped nanoparticles (NPs), have
become one of the burgeoning materials in the recent years due to their anisotropic shape …

Electromagnetic forces and torques enable many key technologies, including optical
tweezers or dielectrophoresis. Interestingly, both techniques rely on the same physical …

We demonstrate theoretically that Fano resonance can induce a negative optical scattering
force acting on plasmonic nanoparticles in the visible light spectrum when an appropriate …

Optical binding is a laser-induced inter-particle force that exists between two or more
particles subjected to off-resonant light. It is one of the key tools in optical manipulation of …

Plasmonic Fano resonances (FRs) in nanostructures have been extensively studied in
recent years. Nanorod-based complexes for FRs have also attracted much attention. The …

The toroidal dipole is an exquisite and untraditional electromagnetic mode, categorizing
separately from the well-known conventional multipole group which can be robustly …

This study demonstrates a method for microparticle optical trapping of silica gel using a
stable Q-switched fiber laser (QFL) pulse. Gold nanoparticle (Au-NP) were fabricated as …

We study the optical far-field and near-field characteristics, and the optical force effects of
plasmonic disk-ring nanostructures. There are multiple Fano features resulting from the …

We demonstrate that resonant optical forces generated within all-dielectric planar photonic
metamaterials at near-infrared illumination wavelengths can be an order of magnitude larger …

We numerically demonstrate that a pronounced dipole–quadrupole (DQ) Fano resonance
(FR) induced lateral force can be exerted on a dielectric particle 80 nm in radius (R sphere …
