Abstract:
The present invention includes microfluidic systems having a microfabricated cavity that may be covered with a removable cover, where the removable cover allows at least part of the opening of the microfabricated cavity to be exposed or directly accessed by an operator. The microfluidic systems comprise chambers, flow and control channels formed in elastomeric layers that may comprise PDMS. The removable cover comprises a thermoplastic base film bonded to an elastomer layer by an adhesive layer. When the removable cover is peeled off, the chamber is at least partially open to allow sample extraction from the chamber. The chamber may have macromolecular crystals formed inside or resulting contents from a PCR reaction. The invention also includes a method for making vias in elastomeric layers by using the removable cover. The invention further includes methods and devices for peeling the peelable cover or a removable component such as Integrated Heater Spreader. Fig. 1B

Abstract:
A variety of elastomeric-based microfluidic devices and methods for using an d manufacturing such devices are provided. Certain of the devices have arrays of reaction sites to facilitate high throughput analyses. Some devices also include reaction sites located at the end of blind channels at which reagent s have been previously deposited during manufacture. The reagents become suspended once sample is introduced into the reaction site. The devices can be utilized with a variety of heating devices and thus can be used in a variety of analyses requiring temperature control, including thermocycling applications such as nucleic acid amplification reactions, genotyping and ge ne expression analyses.

Abstract:
The present invention generally relates to microfluidics and more particularly to the design of customized microfluidic systems using a microfluidic computer aided design system. In one embodiment of the present invention a microfluidic circuit design method is provided. The method includes developing synthesizable computer code for a design. Next, a microfluidic circuit schematic, including a plurality of symbols for microfluidic components, is generated either interactively or using the synthesizable computer code. The microfluidic circuit schematic is then functionally simulated. The microfluidic components are placed and routed on a template to form a physical layout. Then the physical layout is physically simulated using dynamic simulation models of the microfluidic components; and the physical layout is written to a layout file.
