Abstract:
A variety of elastomeric-based microfluidic devices and methods for using and 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 reagents 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 gene expression analyses.

Abstract:
A microfluidic device, with elastomeric components, and having a flow channel, wherein said flow channel has a plurality of blind flow channels opening into and in fluid communication with the flow channel, each blind flow channel having an aperture portion, a channel portion and a terminus portion, and wherein a region at the terminus of each blind flow channel defines a reaction site. Each blind flow channel is associated with a valve that when closed isolates the reaction site from the flow channel. The valves associated with each of the plurality of blind flow channels in fluid communication with the flow channel are under the control of a common control channel and are coordinately closed or opened.

Abstract:
Un dispositivo microfluídico (200), que comprende componentes elastoméricos, y que tiene un canal de flujo (204, 702), en el que dicho canal de flujo tiene una pluralidad de canales de flujo ciego (206) que se abren hacia el interior y están en comunicación de fluidos con el canal de flujo, caracterizándose cada canal de flujo ciego por tener una parte de apertura, una parte de canal, y una parte final, y en el que una región del final de cada canal de flujo ciego define un sitio de reacción (208, 706), en el que cada canal de flujo ciego está asociado con una válvula (212) que cuando se cierra aísla el sitio de reacción del canal de flujo, y caracterizado por que las válvulas asociadas con cada una de la pluralidad de canales de flujo ciego en comunicación de fluidos con el canal de flujo están bajo el control de un canal de control común (210, 712) y se cierran o abren de forma coordinada.
