Journal ArticleDOI
A revolution in optical manipulation
TL;DR: This research presents the next generation of single-beam optical traps, which promise to take optical tweezers out of the laboratory and into the mainstream of manufacturing and diagnostics and even become consumer products.

Tweezers with a twist
Miles J. Padgett,Richard Bowman +1 more
TL;DR: The fact that light carries both linear and angular momentum is well-known to physicists as discussed by the authors, and one application of the linear momentum of light is for optical tweezers, in which the refraction of a laser beam through a particle provides a reaction force that draws the particle towards the centre of the beam.
Journal ArticleDOI
Massively parallel manipulation of single cells and microparticles using optical images.
TL;DR: An optical image-driven dielectrophoresis technique that permits high-resolution patterning of electric fields on a photoconductive surface for manipulating single particles and requires 100,000 times less optical intensity than optical tweezers is presented.
Journal ArticleDOI
Simultaneous micromanipulation in multiple planes using a self-reconstructing light beam
TL;DR: Bessel beams do not diverge and, furthermore, if part of the beam is obstructed or distorted the beam reconstructs itself after a characteristic propagation distance, which may be utilized within optical tweezers to trap particles in multiple, spatially separated sample cells with a single beam.
Journal ArticleDOI
Advances in optical angular momentum
TL;DR: The concept of orbital angular momentum is now leading to new understanding of a wide range of phenomena, including fundamental processes in Bose-Einstein condensates, while the associated technologies have led to new applications in optical tweezing and microscopy as mentioned in this paper.

Direct Observation of Transfer of Angular Momentum to Absorptive Particles from a Laser Beam with a Phase Singularity
TL;DR: Black or reflective particles can be trapped in the dark central minimum of a doughnut laser beam produced using a high efficiency computer generated hologram to carry angular momentum transferred from the central phase singularity beam.

TL;DR: In this paper, the authors demonstrate controlled rotation of optically trapped objects in a spiral interference pattern, which is generated by interfering an annular shaped laser beam with a reference beam.
