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 exotic states. Differently, acoustic tweezers use sound radiation forces to trap particles

Electromagnetic Forces and Torques: From Dielectrophoresis to Optical Tweezers
Chemical Reviews, 2023 Electromagnetic forces and torques enable many key technologies, including optical tweezers or dielectrophoresis. Interestingly, both techniques rely on the same physical process: the interaction of an oscillating electric field with a particle of matter.

Spatially selective manipulation of cells with single-beam acoustical tweezers
Nature Communications, 2020 Acoustical tweezers can exert forces several orders of magnitude greater than optical tweezers but the absence of spatial selectivity and their limited resolution has prevented their use for many applications in microbiology.
