Optical manipulation of particle ensembles in air

TLDR
It is demonstrated that airborne light-absorbing particles can be photophoretically trapped and moved inside an optical lattice formed by multiple-beam interference.
Abstract
We demonstrate that airborne light-absorbing particles can be photophoretically trapped and moved inside an optical lattice formed by multiple-beam interference. This technique allows simultaneous three-dimensional manipulation of multiple micro-objects in gases.

Perspective on light-induced transport of particles: from optical forces to phoretic motion

TL;DR: In this paper, a review of light-induced mechanisms for the controlled transport of microscopic particles is presented, focusing on the direct transfer of momentum between the particles and the incident light waves, on the combination of optical forces with external forces of other nature, and on light-triggered phoretic motion.

Generation of a beam with a dark focus surrounded by regions of higher intensity: the optical bottle beam

TL;DR: A computer-generated hologram is used to form an optical beam with a localized intensity null at its focus that will have applications in the optical trapping of macroscopic objects or atoms; hence the term optical bottle beam.
