MICROFLUIDIC DEVICE WITH LARGE CHANNELS FOR CELL TRANSPORT AND SMALL CHANNELS SUITABLE FOR BIOCHEMICAL PROCESSES

摘要

A microfluidic device for molecular diagnostic analysis of a biological sample containing cells, the microfluidic device having a supporting substrate, a plurality of microsystems technology (MST) channels each with a cross-sectional area between 1 square micron and 400 square microns for biochemical processing of constituents within the biological sample, and, a plurality of cell transport channels, each with a cross-sectional area greater than 400 square microns for receiving the biological sample and transporting cells within the biological sample to predetermined sites in the MST channels.
