The MMI (Molecular- Machines & Industries) CellManipulator is a powerful optical multi-beam optical tweezers system based on the mechanical forces arising from a strongly focused laser beam. It enables comfortable, ultra-precise and contact-free manipulation of microscopic particles, single or living cells, or subcellular organisms and the measurement of intracellular activities. Thus, it can hold, move, rotate, join, separate, stretch or otherwise manipulate up to 2 x10 microscopic objects simultaneously or separately in three dimensions. The wavelength of the laser does not interfere with the integrity of living specimens. Cell sorting and cell positioning can also be accomplished together with the quadrant detector enabling the measurement of binding forces or viscosities at sub cellular level.

Due to multiple ports and dual-level laser integration, the seamless use of different modules and imaging technologies is possible.

Automated quadrant detector calibrations routines allow routine force-distance measurements, so called Force Spectroscopy. A feedback module is available for isometric force detections and force clamping.
