1. A microfluidic device for operations at high field strengths comprising:

  • a substrate having at least one channel and at least one aperture in fluid communication with said channel;

    a cover bonded to said substrate such that a reservoir is formed at said at least one aperture; and

    a driving electrode used to apply a field of at least 400 V/cm comprised of an electrically conducting silver/silver chloride ink pattern on at least one of said substrate and cover such that when a material is present in said channel and reservoir said ink pattern makes electrical contact with said material and such that fewer bubbles form in said channel and reservoir when establishing said field across a driving electrode of bare platinum.
