An optical micromanipulation which comprises trapping, rotating, and transporting 5-mu.m polystyrene microbeads in asymmetric Bessel-Gaussian (BG) laser beams is studied. The beams which carry orbital angular momentum are generated by means of a liquid crystal microdisplay and focused by a microobjective with a numerical aperture of NA = 0.85. Asymmetric BG beams can be used instead of conventional Gaussian beam for trapping and transferring live cells without thermal damage.
