1. A microfluidic pumping device suitable for effecting inkjet printing by ejecting fluid through at least one nozzle in response to activation of a deflectable membrane, said device comprising:

  • an actuator operatively coupled to said membrane and containing at least one electrolytic fluid; and

    , at least one nanostructure contained in said electrolytic fluid;

    wherein, said nanostructure is adapted to deflect toward said membrane in response to an operating voltage being applied to at least said nanostructure thereby deflecting said membrane and causing said fluid to be ejected through said nozzle.
