Abstract: We demonstrate the optical manipulation of biological particles using a low-order LP 21 fiber mode. The focused four-lobed LP 21 mode distribution was theoretically and experimentally found to be effective in optical tweezer applications, including selective cellular pick-up, pairing, grouping or separation, as well as rotation of cell dimers and clusters. Our proposed theoretical model estimates both the translational dragging force and rotational torque in good accordance with experimental data. With a simple all-fiber configuration, and low peak irradiation to target bioparticles, the proposed LP 21 'optical chuck' system has great application potential in biological test systems.
