FIG. 1.

Overview of a microfluidic micropipette aspiration device. (a) Overall schematic of the multilayer device with main microfluidic channel (blue) and pneumatically actuated control valves (yellow). (b) Three-dimensional sketch of the zoomed-in red box in (a) showing trapping chambers and microchannels connecting the two main channels. (c) Photo of the device showing dye filled microchannels (scale bar is 2 mm). (d) Bright field image of the zoomed-in green box in (c) showing 2 × 13 trapping chambers (scale bar is 80 μm).
