1] (a) Schematic of the microfluidic device operation and structure. The flow passes under the cell trap, directing the cells into the capture cup. The support pillars maintain the proper vertical gap. (b) Scanning electron micrograph image of the 2 mm x 2 mm device, which contains 1,166 cell traps. (c) Magnified image of the device, showing the densely packed structures. (d) Detail of the trap structure, including the larger front-side and smaller back-side capture cups (14 µm tall, 18µ m wide, 25–40 µm deep, and 10 µm wide by 5 µm deep, respectively), along with support pillars (7.5µ m wide x 35–50 µm long x 6–8 µm tall). (e) Different arrays that can pair and capture thousands of cells in parallel." />
