Abstract
A fluidic device includes a porous substrate, a wetting region extending through a first portion of the porous substrate from a first side of the substrate, in which the wetting region is permeable to fluid transport, and a non-wetting region extending through a second portion of the porous substrate from a second side of the substrate, in which the non-wetting region is operable to switch between a first state impermeable to fluid transport and a second state permeable to fluid transport.
