First claim
Opening claim text (preview).
I claim: 1. A droplet actuator device for conducting droplet operations, comprising: (a) a bottom substrate and a removable top substrate; (b) an array of droplet operations electrodes arranged on the bottom substrate; and wherein the top substrate comprises a self-contained replaceable/removable cartridge for a droplet actuator-based assay; and wherein the cartridge further comprises a dielectric layer interfacing with the droplet operations electrodes of the bottom substrate; and wherein the dielectric layer is replaceable/removable. 2. A droplet actuator device, for conducting droplet operations, comprising: (a) a bottom substrate and a removable top substrate; (b) an array of droplet operations electrodes arranged on the bottom substrate; and wherein the top substrate comprises a self-contained replaceable/removable cartridge for a droplet actuator-based assay; and wherein the cartridge further comprises a dielectric layer interfacing with the droplet operations electrodes of the bottom substrate; and wherein the dielectric layer is patterned to a desired topology that corresponds to a certain arrangement of droplet operations electrodes on the bottom substrate. 3. A droplet actuator device for conducting droplet operations, comprising: (a) a bottom substrate region and a top substrate region; (b) a hinge region comprising a flexible substrate connecting the bottom substrate region and the top substrate region; (c) an array or path of droplet operations electrodes arranged on the bottom substrate region; (d) a dielectric layer selectively disposed atop the droplet operations electrodes; and (e) wherein the hinge region provides a mechanism to fold top substrate region into proximity of bottom substrate region to form a first closed cartridge position, and also provides a mechanism to unfold the top substrate region from the bottom substrate region to form a second open cartridge position. 4. The droplet actuator device of claim 3 , wherein the top substrate region further comprises a ground electrode arranged thereon. 5. The droplet actuator device of claim 4 , further comprising a rigid layer disposed on a surface that is opposite the droplet operations electrodes and ground electrode and excludes hinge region. 6. The droplet actuator device of claim 3 , further comprising a hydrophobic layer disposed as a final layer atop the bottom substrate region, top substrate region, and hinge region. 7. The droplet actuator device of claim 3 , wherein the dielectric layers comprises an adhesive backed polyimide. 8. The droplet actuator device of claim 3 , wherein the top substrate region comprises a self-contained replaceable/removable cartridge.
