Abstract
A microfluidic device having a substrate with an electrically conductive element made using a conductive ink layer underlying a hydrophobic layer.
Claims8
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.

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.
