Optical trapping is an established field for movement of micron-size objects and cells.
However, trapping of metal nanoparticles, nanowires, nanorods and molecules has received …

The excited electronic states of noble metal Au and Ag nanocrystals are very different than
those of molecules. Ag and Au nanocrystal optical transitions (plasmons) in the visible can …

Optical trapping has widely affected both the physical and life sciences. Past approaches to
optical trapping of nanoscale objects required large optical intensities, often above their …

This Perspective describes recent progress in optical trappings of nanoparticles based on
localized surface plasmon. This plasmonic optical trapping has great advantages over the …

Optical trapping is the craft of manipulating objects with light. Decades after its first inception
in 1970, the technique has become a powerful tool for ultracold‐atom physics and …

Nonlinear responses of nanoparticles induce enlightening phenomena in optical tweezers.
With the gradual increase in optical intensity, effects from saturable absorption (SA) and …

We demonstrate three-dimensional trapping and orientation of individual Au nanorods by
using laser light slightly detuned from their longitudinal plasmon mode. Detuning to the long …

Optical trapping and manipulation have been widely applied to biological systems, and their
cutting-edge techniques are creating current trends in nanomaterial sciences. The resonant …

We present an experimental and theoretical study of the coherent Rayleigh-Brillouin
scattering in gases in the kinetic regime. Gas density perturbation waves were generated by …

Nanoaperture optical tweezers are emerging as useful label-free, free-solution tools for the
detection and identification of biological molecules and their interactions at the single …
