Patent ID: 8173415

Claim:
A microinjection device for injecting a target cell with a reagent, the microinjection device comprising: 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 an injected position and an un-injected position 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.
