The invention herein provides a picoliter fluid pumping device in combination with an electrophoresis unit. The picoliter fluid pumping device includes an actuating unit, for selectively generating pump actuating signals, and a pump unit. The pump unit includes a deforming means, a deformable fluid chamber having a deformable chamber segment, a nozzle port, and an inlet port coupled to a fluid source to provide a fluid to the deformable fluid chamber. The deforming means, coupled to the actuating unit, deforms the deformable chamber segment in response to a pump actuating signal to cause a picoliter quantity of the fluid to be emitted from the nozzle port. The picoliter fluid pumping device has in combination an electrophoresis unit having at least one electrophoresis electrode coupled to the deformable fluid chamber and spatially located near the nozzle port and at least one electrophoresis port coupled to the deformable fluid chamber and spatially located near the nozzle port.
