    "abstract": "We demonstrate optical trapping and manipulation of defects and transparent\nmicrospheres in nematic liquid crystals (LCs). The three-dimensional director\nfields and positions of the particles are visualized using the Fluorescence\nConfocal Polarizing Microscopy. We show that the disclinations can be\nmanipulated by either using optically trapped colloidal particles or directly\nby tightly-focused laser beams. We employ this effect to measure the line\ntensions of disclinations.",
