Laser Optical Tweezers:
The MMI CellManipulator uses a Ytterbium infrared laser with a long wavelength with up to 10 W of trapping power. The wavelength of the laser does not interfere with the integrity of living specimens. The intensely-focused laser beam can hold, move, rotate, join, separate, stretch or otherwise manipulate in three dimensions upto ten microscopic objects simultaneously. The particles suspended in liquid can range from 0.2 to 200 microns.
