The technical development of optical tweezers, along with their application in the biological and physical sciences, has progressed significantly since the demonstration of an optical trap for micron-sized particles based on a single, tightly focused laser beam was first reported more than twenty years ago.

Potential mapping of optical tweezers
Optics Letters, 2011Optical tweezers are very often used for measurement of piconewton range forces. Depending on the displacement of the trapped bead, the trap may become stiffer which causes considerable underestimation of the measured force. We have shown, both by theory and experiment, that such a stiffening occurs for beads larger than 0.5 μm in radius. For the first

Summary form only given. A compact optical tweezer package has been developed for use on a microscope to be flown on the International Space Station as part of a series of experiments in colloid crystalization. A brief introduction to the principles of single-beam optical tweezer operation is presented, after which a detailed system layout is shown ...

The optical tweezer, with the ability to apply force and deformation on a micro scaled object on the order of piconewton (pN, 10~12 N) and nanometer (nm, 10~9 m), is utilized in this study to manipulate primitive myeloblasts from acute myeloid leukemia (AML) patients for biomechanical properties characterization. Mcrobeads are attached to cell surfaces

The craze for miniaturization has swept o’er most every nation, but should a hand e’er so slightly tremble no micro-machine can it assemble: and so all those really small bits leave the technicians in fits and the hope for a lab on a chip might seem frightfully flip. Yet, while optical forces are weak they provide the control that we seek. When light’s

Holographic optical tweezers (HOT) employ a relatively simple form of holographic beam-shaping that produces discrete, point-like intensity peaks in the optical trapping plane, each of which acts as a single optical tweezer. For each tweezer, lateral position and axial position can be determined individually by means of accordingly prepared holograms ...
