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.read more

Advanced optical trapping by complex beam shaping
TL;DR: In this paper, two promising adjacent approaches tackle fundamental limita- tions by utilizing non-optical forces which are, however, induced by optical light fields, namely, dielectrophoretic and photophoretic forces.

Optical trapping and binding
Richard Bowman,Miles J. Padgett +1 more
TL;DR: The underlying theory of optical traps is outlined, and many of the physical observations that have been made in such systems are explored, including 'optical binding', where trapped objects interact with one another through the trapping light field.

Optical trapping and manipulation of single particles in air: Principles, technical details, and applications
TL;DR: In this article, a review of optical configurations for trapping and manipulating single airborne particles in air is presented, and the authors tentatively categorize them into radiation-pressure traps, photophoretic traps, and universal optical traps.

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
Jochen Arlt,Miles J. Padgett +1 more
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.
