Title METHOD AND DEVICE FOR ARRANGING CELLS USING LASER
Abstract Provided are a method and a device for arranging cells using a laser, whereby cells can be arranged so that the cells are prevented from separating from each other. The method according to the present invention comprises: a step for capturing cells using a laser; a step for conveying the captured cells relative to other cells and contacting the cells in a polymer solution that contains a water-soluble polymer in an aqueous solvent; and maintaining the contact among the cells using a depletion effect of the polymer solution. The device according to the present invention comprises: a laser light source; a polymer solution that contains a water-soluble polymer in an aqueous solvent and can exert a depletion effect for maintaining contact among cells; a sample cell for housing the cells and a sample cell; a light condensing lens for condensing the laser in the sample cell; and a moving unit for relatively three-dimensionally moving the sample cell and the light condensing spot of the laser.
