Microfluidic system including a virtual wall fluid interface port for interfacing fluids with the microfluidic system

摘要

A fluid interface port in a microfluidic system and a method of forming the fluid interface port is provided. The fluid interface port comprises an opening formed in the side wall of a microchannel sized and dimensioned to form a virtual wall when the microchannel is filled with a first liquid. The fluid interface port is utilized to perform a labeling operation on a sample.
