Abstract
Articles and methods involving fluidic devices are generally provided. In some embodiments, a fluidic device comprises a first layer comprising first and second regions that are disconnected from each other in the first layer and a second layer comprising a channel in fluidic communication with the first and second regions. The device may also comprise a third layer comprising a channel in fluidic communication with the first and second regions. One or more portions of a channel and/or one or more reagents may comprise a reagent. In some embodiments, a method comprises flowing two or more fluid samples towards each other through a channel. The fluids may meet at an interface and/or may react at an interface.
Claims20
A fluidic device, comprising:
- a first layer comprising first and second regions;
- a second layer comprising a first channel;
- and
- a third layer comprising a second channel in fluidic communication with the first and second regions, wherein:
- the first channel directly fluidically connects the first and second regions;
- the second channel directly fluidically connects the first and second regions;
- the first layer is disposed on the second layer;
- the third layer is disposed on the first layer;
- the first and second regions are disconnected from each other in the first layer;
- at least one of the first layer, second layer, and third layer comprises a porous material;
- the first channel is in fluidic communication with the second channel via the first region and via the second region;
- the first channel is positioned on both the first region and the second region;
- and
- the second channel is positioned on both the first region and the second region.
A fluidic device, comprising:
- a first layer comprising first and second regions;
- a second layer comprising a single first channel;
- and
- a third layer comprising a single second channel in fluidic communication with the first and second regions, wherein:
- the first layer is disposed on the second layer;
- the third layer is disposed on the first layer;
- the first and second regions are disconnected from each other in the first layer;
- the first and second regions are in fluidic communication with the first channel;
- at least one of the first layer, second layer, and third layer comprises a porous material;
- the first channel is in fluidic communication with the second channel via the first region and via the second region;
- the first channel is positioned on both the first region and the second region;
- and
- the second channel is positioned on both the first region and the second region.
