The mmi CellManipulator from Molecular Machines & Industries (MMI) AG is an optical trap that enables ultraprecise contact-free manipulation of microscopic particles. The multibeam tweezers use a focused laser beam to trap, move and position single cells or subcellular and microscopic particles in sizes from ~0.1 to 200 μm. Applications include cell sorting and fusion, measurement of binding forces or viscosities, measurement of cell-cell interactions and study of subcellular movement. The system can be combined as a module with the laser microdissection instrument mmi Cellcut.
