A microinjection device for injecting a target cell with a reagent. The microinjection device includes a flexible substrate; a target supply channel formed in the flexible substrate for receiving the target cell; a reagent supply channel formed in the flexible substrate for receiving the reagent; a suction capillary mounted within a suction channel formed in the flexible substrate, the suction capillary providing suction to the target supply channel for immobilizing the target cell within the target supply channel; an injection needle mounted within a needle channel formed in the flexible substrate, the injection needle being movable between injected and un-injected positions by deforming at least a part of the flexible substrate; and a plurality of electrodes embedded in the flexible substrate, the plurality of electrodes creating a voltage potential across the injection needle to move the reagent into the target when the injection needle is in the injected position.
