Droplet operations platform
First Claim
1. A droplet actuator device comprising:
- a. a bottom substrate and a top substrate separated from each other to form a gap therebetween;
b. an arrangement of droplet operations electrodes, on one of the bottom substrate and the top substrate, configured for conducting droplet operations thereon;
c. one or more heater elements in proximity to and aligned with one or more of the droplet operations electrodes in a manner which permits establishment of temperature control in the gap in vicinity of the one or more droplet operations electrodes;
d. one or more temperature control zones in the gap, wherein each of the one or more temperature control zones is established by at least one metal layer structure provided within or on a surface of the bottom substrate, and distinct from the droplet operations electrodes, wherein the metal layer structure is distinct from the one or more heater elements and arranged to control distribution of heat in the gap.

Abstract
The invention relates to a droplet actuator device and methods for integrated sample preparation and analysis of a biological sample. A droplet actuator device is provided for conducting droplet operations. The droplet actuator device may include a bottom substrate and a top substrate separated from each other to form a gap therebetween; an arrangement of droplet operations electrodes arranged on one or both of the bottom and/or top substrates for conducting droplet operations thereon; a reagent storage layer comprising one or more compartments bound to the top substrate; and one or more openings arranged to provide a fluidic path from the one or more compartments into the gap, upon breach of a breachable seal separating the one or more compartments and openings.
