METHOD FOR TREATING CELL

PROBLEM TO BE SOLVED: To provide a method for treating cells, capable of controlling a shape of arrangement of the cells, capable of transferring the cells grounded on a basal plate by laser trapping, and therefore extremely effective as a cell manipulation procedure in fusion treatment of the cells, etc. SOLUTION: This method for treating the cell includes a process for applying an alternating voltage to a space which is supplied with a suspension containing a plurality of the cells and positioned between electrodes facing each other and a process for transferring the cells between the electrodes by the laser trapping, wherein the process for transferring the cells by the laser trapping is conducted prior to application of the alternating voltage, or during the application, and manipulation for making the cells conform to a desired arrangement from an initial state is conducted in the laser trapping prior to the application.
