Holographic acoustic tweezers [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Holographic optical tweezers use focused light to manipulate multiple objects independently without contact. They are used in tasks such as measuring the spring constant of DNA, the pulling force of the kinesin protein, or to trap matter in ...

Theory of Optical Tweezers [PDF]
Europhysics Letters (EPL), 1999 We derive a partial-wave (Mie) expansion of the axial force exerted on a transparent sphere by a laser beam focused through a high numerical aperture objective. The results hold throughout the range of interest for practical applications.

Deep learning for optical tweezers
NanophotonicsOptical tweezers exploit light–matter interactions to trap particles ranging from single atoms to micrometer-sized eukaryotic cells. For this reason, optical tweezers are a ubiquitous tool in physics, biology, and nanotechnology.

Optical tweezers: theory and practice [PDF]
The European Physical Journal Plus, 2020 The possibility for the manipulation of many different samples using only the light from a laser beam opened the way to a variety of experiments. The technique, known as Optical Tweezers, is nowadays employed in a multitude of applications demonstrating ...

Optical tweezers throw and catch single atoms [PDF]
Optica, 2022 Single atoms movable from one place to another would enable a flying quantum memory that can be used for quantum communication and quantum computing at the same time. Guided atoms, e.g., by optical tweezers, provide a partial solution, but the benefit of

Optical tweezers in a dusty universe [PDF]
The European Physical Journal Plus, 2021 AbstractOptical tweezers are powerful tools based on focused laser beams. They are able to trap, manipulate, and investigate a wide range of microscopic and nanoscopic particles in different media, such as liquids, air, and vacuum. Key applications of this contactless technique have been developed in many fields. Despite this progress, optical trapping

Quantum Tweezer for Atoms [PDF]
Physical Review Letters, 2002 We propose a quantum tweezer for extracting a desired number of neutral atoms from a reservoir. A trapped Bose-Einstein condensate (BEC) is used as the reservoir, taking advantage of its coherent nature, which can guarantee a constant outcome. The tweezer is an attractive quantum dot, which may be generated by red-detuned laser light.

Laser Scissors and Tweezers to Study Chromosomes: A Review
Frontiers in Bioengineering and Biotechnology, 2020 Starting in 1969 laser scissors have been used to study and manipulate chromosomes in mitotic animal cells. Key studies demonstrated that using the “hot spot” in the center of a focused Gaussian laser beam it was possible to delete the ribosomal genes ...
