MICROFLUIDIC EXTRACTION DEVICE HAVING A STABILIZED LIQUID/LIQUID INTERFACE

摘要

A microfluidic device for extraction of analytes of interest from a carrier liquid in a liquid solvent, the two liquids forming an interface between micro-pillars in an extraction chamber. The carrier liquid forms a wetting angle theta1 on the micro-pillars and a bottom wall of the extraction chamber, and a wetting angle theta2 on a top wall, the wetting angles satisfying equation 45°@(theta1+theta2)/2@135°.
