MICROFLUIDIC DEVICE AND METHOD FOR CONTROLLING INTERACTION BETWEEN LIQUIDS

摘要

A microfiuidic device comprises a valve having electrically controllable wetting properties. The valve comprises a valve surface arranged in a closed valve space defined by at least the valve surface, a first liquid opening for leading a first liquid to the valve and a second liquid opening for leading a second liquid to the valve. The valve surface, in a first state, is sufficiently hydrophobic to prevent contact between the first liquid and the second liquid. The valve surface, in a second state, is sufficiently hydrophilic to allow contact between the first liquid and the second liquid. A ventilation outlet is provided for allowing gas to escape from the valve space.
