    "abstract": "Optical tweezers are widely used for the manipulation of cells and their\ninternal structures. However, the degree of manipulation possible is limited by\npoor control over the orientation of trapped cells. We show that it is possible\nto controllably align or rotate disc shaped cells - chloroplasts of Spinacia\noleracea - in a plane polarised Gaussian beam trap, using optical torques\nresulting predominantly from circular polarisation induced in the transmitted\nbeam by the non-spherical shape of the cells.",
