Microfluidic Chip (IMAGE) University of Pennsylvania Caption Using lithography to simultaneously etch 10,260 devices into a four-inch silicon wafer, sandwiching it between two glass plates to make hollow channels, and hooking up its single sets of inlets and outlets, the Penn team's system produces an effective flow rate than is more than ten thousand times faster than what can be typically achieved in a microfluidic device.
