DEP Force Control And Electrowetting Control In Different Sections Of The Same Microfluidic Apparatus

A process of operating a fluidic apparatus comprising an enclosure for containing liquid media, said process comprising:

• inducing a net dielectrophoresis (DEP) force on a micro-object in a first liquid medium on a first surface in a first section of said enclosure;
• and
• changing a wetting property of a region of an electrowetting surface on which a second liquid medium is disposed in a second section of said enclosure.

A process of operating a fluidic apparatus having an enclosure that comprises a first surface and an electrowetting surface, said process comprising:

• drawing a droplet of a first liquid medium disposed on said first surface in a first section of said enclosure into a second medium disposed on said electrowetting surface in a second section of said enclosure,
• wherein said drawing comprises changing an electrowetting characteristic of a region of said electrowetting surface at a boundary with said first surface to induce a sufficient force at said region on said droplet to draw said droplet across said boundary and into said second liquid medium.
