Providing DEP Manipulation Devices And Controllable Electrowetting Devices In The Same Microfluidic Apparatus

A process of operating a microfluidic apparatus comprising a chamber, dielectrophoresis (DEP) devices, and electrowetting (EW) devices, said process comprising:

• moving a micro-object from a first outer surface of a first of said DEP devices to a second surface of a second of said DEP devices by activating said second DEP device and thereby creating a net DEP force on said micro-object in a direction of said second DEP device;
• and
• moving a droplet of a liquid medium from a first location to a second location in said chamber by activating a second of said EW devices and thereby changing a wetting property of a second electrowetting surface of said second EW device,
• wherein:
• in said first location said droplet is disposed in part on a first electrowetting surface of a first of said EW devices but not on said second electrowetting surface of said second EW device, and
• in said second location said droplet is disposed in part on said second electrowetting surface of said second EW device but not on said first electrowetting surface of said first EW device.
