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 ...
