Abstract
Articles and methods involving fluidic devices are generally provided. In some embodiments, a fluidic device comprises a first layer comprising a central region in fluidic communication with an environment external to the fluidic device. The first layer may also comprise a first channel and a second channel in fluidic communication with the central region and extending radially outwards therefrom. The first and second channels may comprises first and second sample regions from which first and second samples can be removed from the fluidic device. In some embodiments, a fluidic device comprises a first layer and a second, filtration layer configured to separate blood cells from plasma positioned between the environment external to the fluidic device and the first layer. In some embodiments, a fluidic device comprises a layer configured to distribute fluid from the region in fluidic communication with the environment external to the fluidic device laterally across the layer positioned between two porous, absorbent layers.
