A COMBINED WETTING/NON-WETTING ELEMENT FOR LOW AND HIGH SURFACE TENSION LIQUIDS

摘要

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