Abstract
Abstract Disclosed is a cell manipulating apparatus for conveying cells to a plurality of chambers provided in a chamber plate. The apparatus comprises a taking-up device adapted to take up cells to the respective taking up portions of a carrier plate placed in positions corresponding to those of said chambers in the chamber plate and a moving device adapted to move, relatively with respect to the chamber plate, the taking-up device to a position above the chamber plate. The taking-up portions may be effectively composed of pressure-controlled cavities or SiO 2 films provided in the carrier plate.
