Reconfigurable multi-component micromachines driven by optoelectronic tweezers [PDF]

Nature Communications, 2021
There is great interest in the development of micromotors which can convert energy to motion in sub-millimeter dimensions. Micromachines take the micromotor concept a step further, comprising complex systems in which multiple components work in concert ...

Acoustic Tweezers for Particle and Fluid Micromanipulation

Annual Review of Fluid Mechanics, 2020
Acoustic tweezers powerfully enable the contactless collective or selective manipulation of microscopic objects. Trapping is achieved without pretagging, with forces several orders of magnitude larger than optical tweezers at the same input power ...

Single-Molecule Studies of Protein Folding with Optical Tweezers

Annual Review of Biochemistry, 2020
Manipulation of individual molecules with optical tweezers provides a powerful means of interrogating the structure and folding of proteins. Mechanical force is not only a relevant quantity in cellular protein folding and function, but also a convenient ...

Efficient characterization of red blood cell rheological properties using a multichannel microfluidic chip and optical tweezers

Materials Today Advances
The rheological properties of red blood cells (RBCs) are crucial for human health. Combining optical tweezers with microfluidics provides a non-contact, sensitive, and high-throughput method for studying RBC rheology.

Formation of Ultracold Molecules by Merging Optical Tweezers. [PDF]

Physical Review Letters, 2023
We demonstrate the formation of a single RbCs molecule during the merging of two optical tweezers, one containing a single Rb atom and the other a single Cs atom.

Optical Frequency Tweezers [PDF]

Physical Review Applied, 2022
We show a concept of optical frequency tweezers for tweezing light in the optical frequency domain with a high resolution, which is the frequency version of the optical tweezers for spatial manipulation of microscopic objects. We report the proof-of-principle experiment via frequency conversion inside a cavity only for the converted light.
